Release notes for v2.5.6-pre2
Summary of changes from v2.5.6-pre1 to v2.5.6-pre2
============================================
(02/02/22 1.369.9.1)
Add JFS file system
(02/02/22 1.369.9.2)
Fix a corruption problem in the jfs dir table
(02/02/22 1.369.9.3)
bi_end_io prototype change
(02/02/22 1.369.9.4)
Remove redundant test from jfs_link
(02/02/25 1.375.1.1)
Clean up ARM TLB handling code; previously there was a lot of code
replication across each processor type, each handling alignment of
addresses slightly differently. We unify this mess, and allow for
greater flexibility in the per-CPU architecture TLB handlers.
We also start to remove the ARM cache.h -> cpu_*.h -> proc-fns.h mess
making the code cleaner and easier to follow.
Documentation describing the expected behaviour of each TLB function
for the 32-bit ARM processors is also included.
(02/02/25 1.375.1.2)
Fix nwfpe so GDB can debug user space floating point again.
Patch 960/1 (Peter Teichmann):
NWFPE patch to be more compliant to IEEE-754
1. The RND/URD instruction was handled as int_to_float(float_to_int
(number)) which is wrong because it only works for floating point
numbers that fit in an integer.
2. The FLT instruction was setting the rounding precision for
extended precision calculations, which is not necessary
(probably a historic relict) but has undesirable side effects
on all extended precision calculations.
(02/02/25 1.375.1.3)
ARM preempt and scheduler fixups for 2.5.5
(02/02/25 1.375.1.4)
Numerous ARM build fixes, small updates and cleanups.
(02/02/25 1.375.1.5)
Rationalise interrupt handling on ARM. With the old code, we had
loops within loops within loops checking until each IRQ level didn't
have any more interrupts for us. This caused both latency problems,
and locked out any chance of handling a second interrupt from down
the chain while one on that chain was already in progress.
The new structure splits out the machine specific IRQ handlers from
the Linux driver specific IRQ handlers, giving the machine specific
handlers much greater flexibility in handling the interrupt. We
also suck the SA1100 IRQ edge selection function into the IRQ core.
(02/02/25 1.375.1.6)
EPXA10DB/Camelot ARM machine updates.
(02/02/25 1.375.1.7)
Add ARM BadgePAD4 machine support.
(02/02/25 1.375.1.8)
Add support for Stork machine type to ARM architecture.
(02/02/25 1.375.1.9)
Add ARM support for Fortunet machine type.
(02/02/25 1.375.1.10)
Update Shark machine type.
(02/02/26 1.398)
[PATCH] x86-64 update for 2.5.5
This patch makes x86-64 compile in 2.5.5 and syncs it with changes in the i386
port. It also fixes some bugs that were discovered in recent testing:
- enhance 32bit emulation and fix bugs.
- fix security hole in vmalloc handling
- Do not use lockless gettimeofday for now because it is buggy.
The patch only changes x86_64 specific files.
-Andi
(02/02/26 1.399)
[PATCH] x86_64 irqstat change
x86_64 does not have an irq_stat array. It puts the interrupt information
into its per CPU area instead, allowing more efficient access to it.
This patch allows the architecture to overwrite
the __IRQ_STAT access macro in linux/irq_cpustat.h.
It is required to make the x86_64 port compile.
-Andi
(02/02/26 1.400)
[PATCH] Linux Secondary Slave IDE timings
This fix is from Dave Bogdanoff .
Linux incorrectly sets up IDE timings for secondary slave drives on PC
systems that use Intel PIIX Southbridges.
This will correctly shift IDE slave PCI timings for register 44h so
that:
- secondary slave (drive1) uses bits 4-7
- primary slave (drive1) uses bits 0-3
(The addition of the parentheses is needed so the shift will take
place after the bitwise-or. Without the parentheses, the shift will
incorrectly always take place before the bitwise-or.)
(02/02/26 1.369.11.1)
[PATCH] Input patch - joystick drivers update
As a step in the process of updating all the linux input drivers to the
most recent version available, this patch updates all the joystick
drivers that are in the kernel tree.
Changes are mainly the input hotplug/proc support in every of the
joystick drivers, and fixing trivial bugs here and there. I can supply a
more detailed description upon request.
(02/02/26 1.402)
[PATCH] PATCH 1/16: NFSD: Compilation Fix
Fix include file so syscall compiles when NFSD not configured
(02/02/26 1.403)
[PATCH] PATCH 2/16: NFSD: BKL Removal: Lock export table
Change export table lock to (SMP safe) rwsemaphore
As a first step to removing the BKL from nfsd, this patch
changes the lock used for the export table to be a rwsem semaphore.
Previously it had the same functionality but depended on the BKL
for correctness.
As there is no "down_write_interruptible" this patch removes the
posibility of interrupting the write_lock request, but this should
never be needed anyway.
(02/02/26 1.404)
[PATCH] PATCH 3/16: NFSD: BKL Removal: Reply Cache lock
Lock reply cache with SMP safety.
As a second step to removing the BKL from nfsd, this patch
protects the reply cache with a spinlock.
This patches also removed cache_initialised as it
is not longer needed (due to earlier patch).
(02/02/26 1.405)
[PATCH] PATCH 4/16: NFSD: BKL Removal: Locking in nfssvc.c
Tidy up locking in nfssvc - preparing for BKL removal
- nfsd_busy becomes atomic_t
- nfsd_call_lock created to protect timing of calls and stats gathering
- lock_kernel around thread creation and destruction. It is
sufficiently uncommon that it doesn't really need a lock of it's
own. It is currently under the BKL because all of the nfsservctl
syscall is, but that is about to be removed so we preserve BKL here.
(02/02/26 1.406)
[PATCH] PATCH 5/16: NFSD: BKL removal: add BKL where needed in filehandle lookup
Protect dentry attachement from BKL
The process of attaching a dentry into the dcache
still needs the BKL I think.
When all the other BKL changes in the VFS settle down, I
will revisit this. But as it is not a very frequent
operation, the BKL wont hurt.
Also add a down/up of i_sem when doing a lookup(".."),
as it is down for all other lookups.
(02/02/26 1.407)
[PATCH] PATCH 6/16: BKL removal: Lock read-ahead cache
Protect read-ahead cache with SMP safe locking
As another step to removing the BKL from nfsd, this patch
protects the read-ahead cache with a spinlock.
(02/02/26 1.408)
[PATCH] PATCH 7/16: NFSD: BKL removal: Discard high level BKL locking
Remove last unneeded bit of BKL from knfsd
Remove BKL from nfsservctl systemcall. All
components have their own locking.
Also remove it from the body of nfsd threads. Keep
it for final thread destruction though.
(02/02/26 1.409)
[PATCH] PATCH 8/16: NFSD: RPC lists tidyup
Change sunrpc to use more list.h lists
The sunrpc client code uses home-grown doubly linked
lists to group
- idle server threads
- pending server sockets
- waiting rpc tasks
- all rpc tasks.
This patch converts all of these lists to lists and
also makes the list of all server sockets for a particular server into
a list.h list instead of a single-link list.
Possibly the least obvious change is replacing RPC_INIT_WAITQ
with RPC_WAITQ and INIT_RPC_WAITQ. These follow the model of
LIST_HEAD and INIT_LIST_HEAD defined in list.h and are needed
to initialise the list_head in the rpc_waitq properly.
(02/02/26 1.410)
[PATCH] PATCH 9/16: NFSD: RPC init tidyup
Get sunrpc to use module_init properly
rpc_register_sysctl was called in several places.
Now only once.
(02/02/26 1.411)
[PATCH] PATCH 10/16: NFSD: TCP: rationalise locking in RPC server routines
Tidy up SMP locking for svc_sock
sk_lock is not necessary and is now removed.
The only things that were happening under sk_lock but
not the more global sv_lock were testing and setting
some of the flags: sk_busy, sk_conn, sk_data etc.
These have been changed to bits in a flags word which are atomically
set and tested.
Also, by establishing some simple rules about that must
be done after setting these flags, the locking is not needed.
With this patch sk_conn and sk_data are now flags, not counts (sk_data
was already a flag for udp). They are set if there might be
a connection or data, and only clear when we are sure there aren't
(or when we are about to check if there is).
svc_sock_accepted becomes identical to svc_sock_recieved and
so is discarded in favour of the latter.
sk_rqstp was never used and is now gone.
(02/02/26 1.412)
[PATCH] PATCH 11/16: NFSD: TCP: close bad connections
Detect and close tcp connections that we cannot work with.
If an rpc fragment that arrives on a tcp connection
is non-terminal or too large for our buffer, then we
have to close the connection.
Also, if a write fails on a tcp connection, we close
the connection.
(02/02/26 1.413)
[PATCH] PATCH 12/16: NFSD: TCP: Close idle TCP connections
Close idle rpc/tcp sockets
We split the list of sv_allsocks into two, one
of permanent sockets (udp, tcp listener) and one
of temporary sockets (tcp data).
Whenever we complete a successful receive on a temp socket,
it gets pushed to the end of the list.
Whenever a thread wants to do something, it first checks if
the oldest temp socket has not has a receive for 6 mintutes
(should possibly be configurable). It so, we simulate
a close.
Finally we make sure that threads wake up every few minutes
so that if the server is completely idle, all temp
sockets will get closed.
(02/02/26 1.414)
[PATCH] PATCH 13/16: NFSD: TCP: Reserve space on sndbuf so we never block when writing
Make sure there is alway adequate sndbuf space for replies.
We keep track of how much space might be needed for replies
and never dequeue a request unless there is adequate space
for a maximal reply. We assume each request will generate a maximal
sized reply until the request is partly decoded.
Each RPC program/procedure can specify the maximum size
of a reply to the precedure (though they don't yet).
The wspace callback is used to enqueue sockets that may be waiting
for sndbuf space to become available.
As there should always be enough buffer space to the full
reply, the only reason that sock_sendmsg could block is due
to a kmalloc delay. As this is likely to be fairly quick (and if
it isn't the server is clagged anyway) we remove the MSG_DONTWAIT
flag, but set a 30 second timeout on waiting. If the wait
ever times out, we close the connection. If it doesn't we can
be sure that we did a complete write.
When a request completes, we make sure that the space
used for the reply does not exceed the space reserved. This
is an internal consistancy check.
This patchs sets the sndbuf and rcvbuf sizes for all sockets
used for rpc service. This size if dependant on the servers bufsize (S) and
partially on the number of threads (N).
For UDP
sndbuf == 5*S
rcvbuf == (N+2)*S
for TCP
sndbuf == N*S
rcvbuf == 3*S
see code for rationale (in comments).
(02/02/26 1.415)
[PATCH] PATCH 14/16: NFSD: TCP: Declare max response sizes for NFS and NLM
Declare response sizes for nfs/lockd requests
This allows sndbuf reservation to be more accurate.
For lockd we just say "0" for now, meaning assume the max.
This could be improved, but it isn't critical.
(02/02/26 1.416)
[PATCH] PATCH 15/16: NFSD: TCP: Limit number of active tcp connections to an RPC service
Limit number of active tcp connections to an RPC service
If a connection comes in and that results in number of
connections being more than 5 times the number of threads,
then we close a connection.
We randomly drop with the oldest or the newest connection.
Thus if we are flooded with connection requests, some will
get in and hopefully stay long enough to service at least one request.
(02/02/26 1.417)
[PATCH] PATCH 16/16: NFSD: TCP: enable NFS over TCP via config option
Enable NFS over TCP via config option
(02/02/26 1.418)
update version
(02/02/26 1.419)
[PATCH] updates.
Forward ports from 2.4, Various janitor bits, and some fixes by me to
make the thing work again in 2.5. I munged the MTDRAM driver to work
also (seperate patch to follow), and it seems to work.
David Woodhouse gave this the once over, and approved the changes.
Complete changelog below:
o Don't create two slabcaches with the same name.
o Don't corrupt eraseblock lists on mount
o Don't mark nodes obsolete during mount
o __attribute__((packed)) on the node definitions.
o Fix up() without down() in jffs2_readdir().
o Fix duplicate version number usage - s/highest_version++/++highest_version/
o Fix (i.e. implement) mtime/ctime on directories.
maybe too busy with the bk stuff
o Don't allow hardlinks of directories.
o s/(mode&S_IFMT)==S_IFLNK/S_ISLNK(mode)/ et al to keep Al happy.
o Fix for garbage-collection of holes, where we used to write nodes out
with csize/dsize swapped. Workarounds for existing such brokenness.
o Improve wear levelling by rotating node lists on mount, to avoid starting
at one end of the flash every time.
o Remember to get internal inode-semaphore on symlink operations.
(02/02/26 1.420)
[PATCH] MTD update.
Numerous bugfixes brought forward from 2.4. I added some quick bio fixes
to mtdblock.c, which seemed to work for me whilst testing JFFS2 changes.
(02/02/26 1.421)
[PATCH] 2.5 scsi changes : qlogicfas.c fixed (resend)
This patch allows my qlogic pcmcia scsi card to compile again, as broken
by the recent scsi layer changes.
Despite davem's apparent suggestion that it'd be better to rewrite the
driver, i'd rather not _just_ right now :)
/ Brett Pemberton
(02/02/27 1.423)
Merge AMD7xx PCI compliance quirk fix from 2.4.18.
(02/02/27 1.422.1.1)
PCI Hotplug Core cleanups:
- pcihpfs cleanup, removing unneeded file operations.
- Added facility to have the files change their timestamps if the data
within the file changes.
(02/02/27 1.422.1.2)
Compaq PCI Hotplug controller driver:
- changed proc entry creation to use the proper parent directory variable.
(02/02/27 1.422.1.3)
Added new IBM PCI Hotplug controller driver.
Written by Irene Zubarev, Tong Yu, Jyoti Shah, Chuck Cole, and me.
(02/02/27 1.422.2.1)
USB auerswald driver:
- changed the minor number the auerswald driver was using, as it was found
out that this number was already in use by another USB driver!
(02/02/27 1.422.2.2)
[PATCH] hid-core and hotplug
This restores a line someone deleted, which
affects hotplugging. Basically this restores
correct/previous behavior: the HID driver only
matches HID devices, not every device that
ever connects.
(02/02/27 1.422.2.3)
misc hcd cleanup
This is minor cleanup; pulls #includes out of files
that aren't intended to compile by themselves.
ehci bandwidth recording
Here's a minor update to the EHCI interrupt scheduler,
recording the bandwidth used by an URB for usbfs.
(02/02/27 1.422.2.4)
PATCH: audio driver urb allocation
This fixes a bug in the audio driver which came from an
incorrect conversion from static to dynamic URB allocation.
It's against 2.5.5
I noticed this while trying to see exactly how ISO transfers
get used. The bug is that while originally the driver statically
allocated several structures {urb + N * iso packet descriptors},
the update forgot to allocate the ISO descriptors.
Likely not many folk noticed this on 32 bit machines, where
sizeof urb == 92, because kmalloc rounds that up to 128,
adding 36 bytes of external padding. The ISO descriptors
took up 32 bytes of that, which "just happened" to already
have been allocated but unused.
(02/02/27 1.422.3.1)
Add dev->change_mtu support, supporting non-standard MTUs (within
hardware limits) to the 8139cp net driver.
(02/02/27 1.422.2.5)
This is another USB API cleanup patch. It's against 2.5.5:
- Moves 8 functions from usb.[hc] to hcd.[hc]
- Also moves some data structures and types
- Now usbdevfs and "old" HCDs #include "hcd.h"
- Minor tweaks to the "hcd" layer (one less FIXME)
- Minor kernel doc and comment cleanups
Basically this continues moving the HCD-only functionality
out of the way of normal USB device drivers. Converging
"usb_bus" and "usb_hcd" (later!) will be a bit easier too.
I did basic sanity tests, there's little to break ... :)
There are still a few functions in usb.c that aren't for
general driver use. They're mostly for enumeration,
in areas where the hub driver and HCD root hubs
need to do various kinds of magic. It wasn't clear
how to decouple those, they can certainly wait.
(02/02/27 1.422.2.6)
uhci.c, speed improvements
Basically, the patch turns switching off FSBR into a lazy operation with
the assumption there will be another transfer shortly afterwards. This
works wonders for usb-storage for instance.
(02/02/27 1.422.2.7)
usb ipaq driver:
Added support for the HP Jornada.
(02/02/27 1.422.2.8)
usb serial core:
- cleaned up some whitespace issues
- changed MOD_INC logic for the generic driver
- the port->sem lock is now taken by the serial core, not the individual
usb-serial drivers. This is to reduce races.
(02/02/27 1.422.2.9)
usb visor driver:
- reworked urb handling, getting rid of lots of code now that we have
proper urb reference counting.
- removed port locks as the usb-serial core now does this.
- added support for the Palm m515 thanks to SilaS
(02/02/27 1.422.2.10)
usb serial drivers:
- removed all usage of port->sem as the usb serial core now does this.
(02/02/27 1.422.1.5)
Update 8139cp net driver copyright, version. Remove dead code
that accidentally crept back into driver.
(02/02/27 1.422.1.6)
Remove unneeded and possibly incorrect PPC-specific code
from e1000 net driver.
(02/02/27 1.422.1.7)
Fix e1000 net driver 64-bit DMA initialization.
(02/02/27 1.425)
Add documentation for CONFIG_FB_TRIDENT.
(02/02/27 1.426)
This patch adds help texts for CONFIG_SERIAL_TX3912,
CONFIG_SERIAL_TX3912_CONSOLE, CONFIG_AU1000_SERIAL_CONSOLE,
CONFIG_AU1000_UART, CONFIG_EUROTECH_WDT to drivers/char/Config.help.
(02/02/27 1.427)
Update sisfb for recent kdev_t changes in 2.5.[01].
(02/02/27 1.422.2.11)
usb core:
- removed debugging statement in usb_free_urb() that I
accidentally left in :(
(02/02/28 1.422.4.1)
Missing parts of 2.5.6-pre1 JFFS2 merge.
(02/02/28 1.430)
Shrink icache more aggressively - if we free the dentries,
go ahead and free the inodes too, don't try to age them any
more (the aging has been done on a dentry level).
(02/02/28 1.431)
[PATCH] 2.5.6-pre1 IDE cleanup 10
This is finishing the cleanup parts already started in ide-clean-9.
It kills the ide_register_module() and ide_unregister_module() as well
as associated idiosyncracies alltogether. It turns out
that this patch is actually fixing a bug which was present in the
driver before: the sub-module initialization functions where called
at least twice - which is an abundance.
Tough there is a bit of global namespace pollution caused by this
patch - but I'm aware of it and will fix it just a bit later.
(The terminology used inside the IDE code is anyway nothing common
else in the linux universum...)
The next targets will be:
1. Code obfuscation by "wrappers" around generic BIO level functions.
2. ide_hwgroup_t - which is only used to serialize multiple
discs on the same interrupt and similar. This is however a tough one.
3. There is a plenty of code waste in the chipset drivers, where there
is baroque informative code for the proc file system for static stuff,
which in fact belongs just to syslog(). In fact the default RedHat
distribution kernel is killing this gratitious abuse of the /proc
concept since a long long time...
I'm still awaiting the day of /proc/GPL, where GPL contains the
full text of it...
(02/02/28 1.432)
[PATCH] 2.5.6-pre1 IDE cleanup 11
1. Start of driver tree usage upon suggestion from Pavel Machek.
This still will needs a lot of further work in the future, but
the current code doesn't hurt anything and allowa Pavel to work
further from the base line. In esp. natively implemented
suspend to file requires this - which I would love to see comming
in,since I'm quite frequently using a notebook myself.
2. Kill the _IDE_C macro, which was playing games on entierly
unnecessary declarations inside of header files in esp ide_modes.h
3. Replace the functionally totally equal system_bus_block() and
ide_system_bus_speed() functions with one simple global
variable: system_bus_speed. This saves quite a significatn amount of
code. Unfortunately this is the part, which is makeing this
patch to appear bigger then it really is...
4. Use ide_devalidate_drive() directly instead of idedisk_revalidate().
5. Kill conditional CONFIG_KMOD as well as some other minor tweaks.
Well this isn't that much in terms of functionality, but it took me
quite q bit of time to catch up on the patch-2.5.5.gz ;-)
(02/02/28 1.433)
[PATCH] 2.5.5 IDE cleanup 12
1. Add some notes to Documentation/driver-model.txt about how and
and where to mount the driverfs.
2. Reorganize and prepare the PCI scanning code for proper device
dependant splitup. Basically tedious cleanup of macro games.
3. Use struct pci_dev name field as the name of PCI host dapaters
instead of invention ambigious IDE special names. This makes
the kernel bootup messages look a bit shifted, since those names are bit
longer, but makes up for consistance and should allow one later
to rearage things to fit into the generic PCI device initialization
mechanisms provided by the kernel.
4. Set 3. Allowed us to make the host chip specific
pci_init_xxx class functions have the proper signature of
module initializers. This will make it possible to make true
modules out of them later.
5. Make some functions in cmd64x.c static which where not used
elsewhere.
6. rename ide_special_settings to trust_pci_irq - this is reflecting
it's functionality better. And make it match the pci device vendor
as well as the device ID. It was a BUG to match only the device id!.
7. Make the chanell setup more tollerant for BIOS-es which don't
report IO and MEM bases properly. The code found previously there
tryed but was inconsistant.
8. Start to use proper terminology in ide-pci.c: host chip, channel,
drive instead of hwif, port, drive...
9. Enlarge the name field from ide_hwif_t to 64 bytes. It was only 6
previously and there where custom names there which where exceeding
this!!! But since we use the proper pci devce name there now instead,
we had to extend the size of this field anyway.
10. Add some explanatory comments and fix misguiding comments here and
there.
11. Kill the proc_ide_write_config and proc_ide_read_config brain
damage! Those where backdoors to the pci configuration registers on PCI
devices and IO registers on directly connected ISA ATA controllers.
They didn't discrement between them!
Access to both of them *simply* doesn't belong into an operating system,
which is supposed to abstract out the access to hardware! Did I mention
that access to both can be done from user land without an IDE special
interface! Any program which was using them (I hardly beleve there is
one) just deserves to loose. The programmer responsible for it
deserves to be fired immediately.
12. Move ide_map_xx and ide_unmap_xx tinny bio level wrappers away
from the "global" ide.h to where those are actually used and kill
trivial wrappers for otherwise generic bio_ routines. Just fighting
code obfuscation. The "rq->bio is used or is not there" brain
damage in ide-taskfile.c has to be fixed later. Possibly by killing
ide-taskfile.c alltogether, becouse this should be a driver for
users and not a driver for ATA disk disaster recovery companys...
13. Kill hwif->pci_devid and hwif->pci_venid. Just use the already
present hwif->pci_dev field instead.
14. Kill unused big switch ide_reinit_drive function. This silly
functon was switching upon every possible device driver cathegory
and calling the correspondng reinit function directly. This
idiocy was fortunately not used.
That's all... Most will be clear if one starts looking at the changes
in ide.h of course...
In contrast to the previous patches this one is actually fixing two
serious bugs.
The next direct step will be to kill the sigle place global PCI device
type recognition list from ide-pci.c by pushing the entries to where
they belong -> the host chips setup modules.
(02/02/28 1.434)
[PATCH] 2.5.6-pre1 IDE clean 13a
This is finally moving the ide-pci.c file into a shape where
the host chip detection lists can finally be moved to where they
belong - into the particular chipset specific files.
This is accomplished, by a rather obivous removal of macro magic,
which was just making entries to the global device type
list nonfunctional, instead of making them conditional on the
corresponding CONFIG_BLHA options.
The second thing was to add a flag field to the device recognition
list, which made it possible to compress many of the
multi || chip id conditionals go away.
The only other file affected is ide.h - here is the change in the size
of the name field, which apparently slipped through ide-clean-12...
(02/02/28 1.435)
[PATCH] 2.5.6-pre1 IDE clean 14
Most importantly this patch is making ide.c use the
new automagic for module initialization lists and further
preparing the rest of the code in question here for proper
module separation. Despite this the CMOS probe has been removed
as well... *Iff*, which I don't expect, this breaks anything
it can be reintroduced easely. During this effort an actual bug
in the initialization of the main module has been uncovered as well.
a quite serious BUG has been tagged in ide-scsi.c as well, but
as far as now I just didn't get along to actually fixing it.
(The patch is big enough as it is).
Details follow:
- Kill *unused* ide_media_verbose() funciton.
- Remove the unnecessary media and supports_dma fields from
ide_driver_t.
- Remove the global name field from ide_driver_t struct by pushing it
down to the places where it's actually used.
- Remove the unused hwif_data field from ide_hwif_t.
- Push the supports_dsc_overlap condition up to the level where it
belongs: disk type as well.
- Make the initialization of ide main ide.c work with the new module
initialization auto-magic instead of calling it explicitly in
ll_rw_block.c This prevents the ide_init() from being called twice. We
have BTW. renamed it to ata_module_init(), since ata is more adequate
then ide and xxx_module_init corresponds better to the naming
conventions used elsewhere throughout the kernel.
This BUG was there before any ide-clean. It was worked around by a
magic variable preventing the second call to succeed. We have removed
this variable in one of the previous patches and thus uncovered it.
- Kill proc_ide_read_driver() and proc_ide_write_driver(). The drivers
already report on syslog which drives they have taken care of. (Or
at least they should). In esp. the proc_ide_write_driver() was just
too offending for me. Beleve it or not the purpose of it was to
*request a particular* driver for a device, by echoing some magic
values to a magic file...
More importantly this "back door" was getting in the way of a properly
done modularization of the IDE stuff.
- Made some not externally used functions static or not EXPORT-ed.
- Provide the start of a proper modularization between the main module
and drivers for particular device types. Changing the name-space
polluting DRIVER() macro to ata_ops() showed how inconsistently the
busy (read: module busy!) field from ide_driver_t
is currently used across the different device type modules.
This has to be fixed soon.
- Make the ide code use the similar device type ID numbers as the SCSI
code :-). This is just tedious, but it will help in a distant
feature. It helps reading the code anyway.
- Mark repettitive code with /* ATA-PATTERN */ comments for later
consolidation at places where we did came across it.
- Various comments and notes added where some explanations was missing.

[PATCH] 2.5.6-pre1: parport PCI card hooks
This patch adds some necessary PCI card hooks. Patch originally from
VScom IIRC.

[PATCH] (1/7) kdev_t removals
* new function - fsync_bdev() (analog of fsync_dev(), but takes
struct block_device * instead of kdev_t. Callers of fsync_dev()
that have struct block_device in question are using fsync_bdev()
now.
* old code for fsync_dev(NODEV) had been moved to sys_sync().
Other callers of fsync_dev(NODEV) are calling sys_sync() now.
* fsync_dev() became a wrapper fro fsync_bdev().
* sync_dev() (not used anywhere in the tree) is gone.
* i2oblock.c had fsync_dev() called in ->release(). Removed.
* s390/block/xparm.c was doing fsync_dev() on its devices in
cleanup_module(). Removed.
(02/02/28 1.441)
[PATCH] (2/7) kdev_t removals
* all remaining callers of sync_inodes() and sync_supers() pass
NODEV as an argument, so we can make them void(void). Dead
code removed.
(02/02/28 1.442)
[PATCH] (3/7) kdev_t removals
* sync_buffers() split in two functions (sync_buffers() and
sync_all_buffers()). Callers of sync_buffers(NODEV) are
using the latter, those who actually pass a device - the former.
* sync_buffers() switched from kdev_t to struct block_device *.

Preempt support and fix ARM build for thread_info changes
(02/02/20 1.369.5.1)
Link status detection fix for natsemi net driver.
Apparently, the LSTATUS bit of BMSR latches low until a management read.
This causes ETHTOOL_GLINK to report no-link on the first read after the
link is connected. (damned QA people catch dumb stuff like this KNOWING
I'll have to fix it). This patch just forces GLINK to mdio_read() twice.
(02/02/20 1.369.2.5)

This patch corrects PCI device id in pci_ids.h for Oxford Semi OX16PCI952
PCI/dual 16950 UART chip, and adds this entry to pci.ids. I downloaded the
datasheet today and verified that 9521 is the correct device id.
(02/02/20 1.369.6.4)
Janitor patch for olympic tokenring driver, to replace the

(02/02/20 1.369.7.6)
[PATCH] uhci.c, one more toggle fix
This patch fixes another toggle bug and reverts the previous bogus
patch which caused compile warnings.
It also adds a quick comment explaining the criteria.
JE
(02/02/20 1.369.7.7)
[PATCH] uhci.c, interrupt unlink in completion
This patch fixes a bug where an interrupt URB is unlinked in the drivers
completion handler and we'll try to resubmit it anyway.
(02/02/20 1.369.7.8)
[PATCH] uhci.c, fix pci dma ordering issue
There was a bug where we unmap the PCI DMA mapping and then sync the
data afterwards. This reverses the ordering as well as insures we don't
unmap the region more than once.
(02/02/20 1.369.7.9)
uhci.c didn't work well with USB storage. It would tend to stall
relatively quickly and sometimes locked up the system. It usually only
took me a couple of tries ripping a CD to reproduce the problem.
I took a long hard look at the locking in uhci.c and decided to clean
it up, fixing a couple of bugs along the way as well as documenting the
locking strategy.
With this patch applies, where I could only rip a CD a couple of times
before causing problems, I was able to rip a CD 12,000 times in a row
successfully, before I stopped it. Not a single error :)
(02/02/20 1.369.7.10)
usb config.help:
- removed an unneeded header. Thanks to Jeff Garzik for pointing this out.
(02/02/20 1.369.7.11)

(with a bit of merge foo from greg)
(02/02/21 1.369.6.5)
Update (ancient) wireless net drivers netwave_cs, wavelan,
and wavelan_cs to new wireless API.
(02/02/21 1.369.6.6)
Update wireless net drivers wavelan and wavelan_cs to directly
use spin_[un]lock_irq{save,restore}, instead of defining static
inline functions to do the same thing (but possibly in a non-portable
way).
(02/02/21 1.373)
cleanups, speedups and fixes. Added support for non-current set_cpus_allowed().
(02/02/21 1.374)
- make i_mmap and i_mmap_shared a list.h list
-
make vma->vm_next_share and vma->vm_pprev_share
a proper list.h list as well.
(02/02/21 1.369.1.15)
make rd.c compile again
(02/02/21 1.369.1.16)
[PATCH] imm.c
2.5.5 Oopses at boot time with a disk in a zipdrive.
With this patch all is fine. I have not read the
patch, certainly not checked it for correctness,
just observed that it works for me.
I think the author is Rich Baum.

[PATCH] 2.5 dropping unneded lock precense check.
After BKL was moved from the VFS into the filesystem's methods in the lookup
call, we do not need to check BKL is actually held (we know it is not).
This patch patch removes unneeded lock_depth check.
Without this patch reiserfs cannot be used on SMP.
(02/02/21 1.369.1.18)
[PATCH] PATCH: scsi driver update for 2.5.5
Here enclosed patch for eata.c, eata.h, u14-34f.c, u14-34f.h
to be applied to lk-2.5.5.
eata.c:
+ Remove any reference to virt_to_bus().
+ Fix pio hang while detecting multiple HBAs.
+ Fixed a board detection bug: in a system with
multiple ISA/EISA boards, all but the first one
were erroneously detected as PCI.
u14-34f.c:
+ Remove any reference to virt_to_bus().
+ Fix pio hang while detecting multiple HBAs.
(02/02/21 1.369.1.19)
[PATCH] Insufficient validity check of fat_read_super() <2>
This patch add the validity check of 2 values (fats, reserved). These
values must not be 0.

[PATCH] proper lseek locking in ALSA, take 3
The attached patch implements proper locking in ALSA lseek methods.
Note ALSA has 3 lseek implementations, but only:
sound/core/info.c :: snd_info_entry_llseek()
requires locking. I wrapped the function in the BKL. According to
Jaroslav Kysela the gus_mem_proc method is only called from above. The
third lseek, in hwdep.c, clearly doesn't need locking. Without this
patch, the above lseek is not safe.
Robert Love
(02/02/21 1.369.1.21)
[PATCH] add lseek changes to fs porting guide
Al updated Documentation/filesystems/porting with 2.5 changes but there
is no mention of lseek. The following patch, against 2.5.5, adds lseek
to the list of functions that no longer are called with the BKL.
Robert Love
(02/02/21 1.369.1.22)
[PATCH] .text.exit linkage errors
A forward-port of all the .text.exit fixes which went into
2.4. Also contains a couple of s/MINOR/minor/ changes.
(02/02/21 1.369.1.24)
[PATCH] missing chunk in lvm-fixes in 2.5.5
the lvm-patch that went into 2.5.5 missed the changes in lvm.h and is
still not compileable. This patch adds those changes. The kernel i'm
running right now has this patch and /var and /home on lvm.
(02/02/23 1.376)
- new, less intrusive and faster migration method:
/*
* This is how migration works:
*
* 1) we queue a migration_req_t structure in the source CPU's
* runqueue and wake up that CPU's migration thread.
* 2) we down() the locked semaphore => thread blocks.
* 3) migration thread wakes up (implicitly it forces the migrated
* thread off the CPU)
* 4) it gets the migration request and checks whether the migrated
* task is still in the wrong runqueue.
* 5) if it's in the wrong runqueue then the migration thread removes
* it and puts it into the right queue.
* 6) migration thread up()s the semaphore.
* 7) we wake up and the migration is done.
*/
(02/02/23 1.377)
- cleanup patch from Hugh Dickins, fix up drivers to use vmalloc_to_page() instead of local hacks of uvirt_to_kva(). (and related fixes.)
(02/02/25 1.375.2.1)
[PATCH] Re: [BUGFIX] handling bad inodes in 2.4.x kernels (fwd)
here's much simpler fix (both 2.4 and 2.5):
(02/02/25 1.379)
Update kernel version and defconfig
(02/02/25 1.380)
[PATCH] (1/3) fs/super.c cleanups
* missing yield() added to grab_super() (on failure exit). Without
that we have a nasty race - if get_sb_bdev() happens just before
we grab ->s_umount in kill_super(), we are going to have
get_sb_bdev() spinning indefinitely long without yielding CPU,
so that kill_super() could make progress (and break the loop).
* in kill_super() code that does actual superblock shutdown is
wrapped in if (sb->s_root) {}. That condition is true for
all old callers of kill_super(), so we don't change existing
behaviour.
* instances of deactivate_super()/remove_super() (after failed
call of foo_fill_super()) are replaced with
up_write(&s->s_umount);
kill_super(s);
- now it becomes legitimate (kill_super() works on such guys and
does exactly what we want).
(02/02/25 1.381)
[PATCH] (2/3) fs/super.c cleanups
Now remove_super() is called only from kill_super(). We move
the code that closes device/drops reference to filesystem type
from remove_super() into its caller.
(02/02/25 1.382)
[PATCH] (3/3) fs/super.c cleanups
Preparation to adding new method:
new helper - shutdown_super(). It is cut from kill_super() and
it had absorbed all actions done with superblock contents -
now kill_super(s) is simply
struct file_system_type *fs = s->s_type;
if (!deactivate_super(s))
return;
shutdown_super(s);
put_filesystem(fs);
and shutdown_super() is going to become a method.
(02/02/25 1.384)
[PATCH] net/wanrouter/wan{proc,main}.c crapectomy
Patch below does the following:
* removes dead code from wanproc.c. When file looks like
#ifdef LINUX_2_4
<800 lines>
#else
<900 lines>
#endif
there's no excuse for keeping all that junk around.
* switches wanproc.c to use of seq_file
* removes dead code from wanmain.c (again, dead == never seen by cc1).
* fixes indentation in both
* removes buttloads of trailing spaces in these files, while we are
at it.
See if it's OK with you...
(02/02/25 1.385)
[PATCH] 2.5.5 Trivial patch: fs/file.c comment
[Alan: also applies to 2.2.x]
William Stearns: linux/fs/file.c comment fix
(02/02/25 1.377.1.1)
migration threads should sleep interruptible.

[PATCH] ->d_parent fixes
Protect d_parent with "dparent_lock", making ready to get rid of
BKL for d_move().
(02/02/25 1.387)
[PATCH] final ->d_parent fixes
OK, here's ->d_parent stuff unrelated to printk. Looking into printk
right now...
(02/02/26 1.389)
Enable parport by default on x86
(02/02/26 1.390)
[PATCH] kdev_t search/replaces.
First batch of various kdev_t related changes that have accumulated on
linux-kernel, and some that got sent directly to me after you dropped them.
Some of these need additional fixes to make them work, Some of them
even to make them compile, but this is one step forward..
I have bio-related fixes for some of these also, I'll push those seperately.
(02/02/26 1.391)
[PATCH] Support /dev/kmem access to vmalloc space (Marc Boucher)
From 2.4.17
(02/02/26 1.392)
[PATCH] Numerous address updates.
Updated maintainers list from Ingo's last ping,
various changed email addresses in code headers.
(02/02/26 1.393)
[PATCH] un'fix' NCR scsi driver.
Linus,
Current driver in your tree has been 'fixed' by someone without
understanding just how broken it was. Numerous fixes were done in 2.4
after the 2.5 split by Alan.
This patch reverts the damage the driver does in your tree, and brings
Alan's 2.4 bits over instead. Downside: It doesn't compile.
Upside: It doesn't pretend to work and corrupt data, and at least
is the right base for people to start fixing.
(02/02/26 1.394)
[PATCH] later DMI scan.
This moves the dmi scan to an earlier stage so that we can trap issues
such as the various laptops that don't like enabling APIC.
It's likely to be useful for trapping other similar early-boot problems.
Originally by Mikael Pettersson
(02/02/26 1.395)
Don't be so verbose about normal lack of modprobe
(02/02/26 1.396)
[PATCH] Patch - sharing RTC timer between kernel and user space (2nd)
This patch to allow using of RTC timer inside the kernel space. We can
use the RTC timer as timing source for ALSA sequencer. Patch by Takashi.
The patch adds these three functions and one structure to rtc.h and
rtc.c:
typedef struct rtc_task {
void (*func)(void *private_data);
void *private_data;
} rtc_task_t;
int rtc_register(rtc_task_t *task);
int rtc_unregister(rtc_task_t *task);
int rtc_control(rtc_task_t *t, unsigned int cmd, unsigned long arg);
