driver needs this. This is already done in 2.4.x
<[email protected]> (02/04/10 1.456.3.1)
[PATCH] 2.5.8-pre3 set_bit cleanup II
This changes over some bogus casts, and converts the ext2, hfs and
minix set-bit macros. Also changes pte and open_fds to hand the
actual bitfield rather than whole structure.
No object code changes
<[email protected]> (02/04/10 1.456.3.2)
[PATCH] 2.5.8-pre3 set_bit cleanup III
This removes gratuitous & operators in front of tty->process_char_map
and tty->read_flags.
No object code changes
<[email protected]> (02/04/10 1.456.3.3)
[PATCH] 2.5.8-pre3 set_bit cleanup IV
This changes everything arch specific PPC and i386 which should have
been unsigned long (it doesn't *matter*, but bad habits get copied to
where it does matter).
No object code changes
<[email protected]> (02/04/10 1.456.3.4)
[PATCH] Velikov/Hellwig radix-tree pagecache
Before the mempool was added, the VM was getting many, many
0-order allocation failures due to the atomic ratnode
allocations inside swap_out. That monster mempool is
doing its job - drove a 256meg machine a gigabyte into
swap with no ratnode allocation failures at all.
So we do need to trim that pool a bit, and also handle
the case where swap_out fails, and not just keep
pointlessly calling it.
<[email protected]> (02/04/10 1.456.3.5)
[PATCH] readahead
I'd like to be able to claim amazing speedups, but
the best benchmark I could find was diffing two
256 megabyte files, which is about 10% quicker. And
that is probably due to the window size being effectively
50% larger.
Fact is, any disk worth owning nowadays has a segmented
2-megabyte cache, and OS-level readahead mainly seems
to save on CPU cycles rather than overall throughput.
Once you start reading more streams than there are segments
in the disk cache we start to win.
Still. The main motivation for this work is to
clean the code up, and to create a central point at
which many pages are marshalled together so that
they can all be encapsulated into the smallest possible
number of BIOs, and injected into the request layer.
A number of filesystems were poking around inside the
readahead state variables. I'm not really sure what they
were up to, but I took all that out. The readahead
code manages its own state autonomously and should not
need any hints.
- Unifies the current three readahead functions (mmap reads, read(2)
and sys_readhead) into a single implementation.
- More aggressive in building up the readahead windows.
- More conservative in tearing them down.
- Special start-of-file heuristics.
- Preallocates the readahead pages, to avoid the (never demonstrated,
but potentially catastrophic) scenario where allocation of readahead
pages causes the allocator to perform VM writeout.
- Gets all the readahead pages gathered together in
one spot, so they can be marshalled into big BIOs.
- reinstates the readahead ioctls, so hdparm(8) and blockdev(8)
are working again. The readahead settings are now per-request-queue,
and the drivers never have to know about it. I use blockdev(8).
It works in units of 512 bytes.
- Identifies readahead thrashing.
Also attempts to handle it. Certainly the changes here
delay the onset of catastrophic readahead thrashing by
quite a lot, and decrease it seriousness as we get more
deeply into it, but it's still pretty bad.
<[email protected]> (02/04/10 1.456.3.6)
[PATCH] page->buffers abstraction
page->buffers is a bit of a layering violation. Not all address_spaces
have pages which are backed by buffers.
The exclusive use of page->buffers for buffers means that a piece of
prime real estate in struct page is unavailable to other forms of
address_space.
This patch turns page->buffers into `unsigned long page->private' and
sets in place all the infrastructure which is needed to allow other
address_spaces to use this storage.
This change alows the multipage-bio-writeout patches to use
page->private to cache the results of an earlier get_block(), so
repeated calls into the filesystem are not needed in the case of file
overwriting.
Devlopers should think carefully before calling try_to_free_buffers()
or block_flushpage() or writeout_one_page() or waitfor_one_page()
against a page. It's only legal to do this if you *know* that the page
is buffer-backed. And only the address_space knows that.
Arguably, we need new a_ops for writeout_one_page() and
waitfor_one_page(). But I have more patches on the boil which
obsolete these functions in favour of ->writepage() and wait_on_page().
The new PG_private page bit is used to indicate that there
is something at page->private. The core kernel does not
know what that object actually is, just that it's there.
The kernel must call a_ops->releasepage() to try to make
page->private go away. And a_ops->flushpage() at truncate
time.
<[email protected]> (02/04/10 1.456.3.7)
[PATCH] writeback daemons
This patch implements a gang-of-threads which are designed to
be used for dirty data writeback. "pdflush" -> dirty page
flush, or something.
The number of threads is dynamically managed by a simple
demand-driven algorithm.
"Oh no, more kernel threads". Don't worry, kupdate and
bdflush disappear later.
The intent is that no two pdflush threads are ever performing
writeback against the same request queue at the same time.
It would be wasteful to do that. My current patches don't
quite achieve this; I need to move the state into the request
queue itself...
The driver for implementing the thread pool was to avoid the
possibility where bdflush gets stuck on one device's get_request_wait()
queue while lots of other disks sit idle. Also generality,
abstraction, and the need to have something in place to perform
the address_space-based writeback when the buffer_head-based
writeback disappears.
There is no provision inside the pdflush code itself to prevent
many threads from working against the same device. That's
the responsibility of the caller.
The main API function, `pdflush_operation()' attempts to find
a thread to do some work for you. It is not reliable - it may
return -1 and say "sorry, I didn't do that". This happens if
all threads are busy.
One _could_ extend pdflush_operation() to queue the work so that
it is guaranteed to happen. If there's a need, that additional
minor complexity can be added.
<[email protected]> (02/04/10 1.456.3.8)
[PATCH] use pdflush for unused inode writeback
This is pdflush's first application! The writeback of
the unused inodes list by keventd is removed, and a
pdflush thread is dispatched instead.
There is a need for exclusion - to prevent all the
pdflush threads from working against the same request
queue. This is implemented locally. And this is a
problem, because other pdflush threads can be dispatched
to writeback other filesystem objects, and they don't
know that there's already a pdflush thread working that
request queue.
So moving the exclusion into the request queue itself
is on my things-to-do-list. But the code as-is works
OK - under a `dbench 100' load the number of pdflush
instances can grow as high as four or five. Some fine
tuning is needed...
<[email protected]> (02/04/10 1.456.3.9)
[PATCH] replace kupdate and bdflush with pdflush
Pretty simple.
- use a timer to kick off a pdflush thread every five seconds
to run the kupdate code.
- wakeup_bdflush() kicks off a pdflush thread to run the current
bdflush function.
There's some loss of functionality here - the ability to tune
the writeback periods. The numbers are hardwired at present.
But the intent is that buffer-based writeback disappears
altogether. New mechanisms for tuning the writeback will
need to be introduced.
<[email protected]> (02/04/10 1.456.3.10)
[PATCH] cramfs cleanup
All places where we do blkdev_size_in_bytes(sb->s_dev) are bogus - we
can get the same information from ->s_bdev without messing with kdev_t,
major/minor, etc.
There will be more patches of that kind - in the long run I'd expect
only one caller of blkdev_size_in_bytes() to survive. One if
fs/block_dev.c, that is - called when we open device.
<[email protected]> (02/04/10 1.456.3.11)
[PATCH] mtdblock fixes
Assorted compile fixes in mtdblock.c
<[email protected]> (02/04/10 1.456.3.12)
[PATCH] jffs2_get_sb() fixes
Fixes races in jffs2_get_sb() - current code has a window when two
mounts of the same mtd device can miss each other, resulting in two
active instances of jffs2 fighting over the same device.
<[email protected]> (02/04/10 1.456.3.13)
[PATCH] more blkdev_size_in_bytes() removals
More places where we want the size of block device and have relevant
struct block_device * available,
<[email protected]> (02/04/10 1.456.2.6)
[PATCH] redo patch clobbered by ACPI
The latest ACPI merge accidentally clobbered another change in pci-irq.c.
Here's the original patch again (applies fine except for an offset)
Thanks -- Andy
<[email protected]> (02/04/10 1.456.2.7)
[PATCH] cciss.c, use pdev->irq after pci_enable_device
Patch to cciss driver in 2.4.8-pre2 to use pdev->irq
and other pci_dev structure elements only after calling
pci_enable_device.
Morten Helgesen <[email protected]> sent me this.
<[email protected]> (02/04/10 1.461)
[PATCH] 2.5.8-pre3 IDE 30
- Eliminate ide_task_t and rename struct ide_task_s to struct ata_taskfile.
This should become the entity which is holding all data for a request in the
future. If this turns out to be the case, we will just rename it to
ata_request.
- Reduce the number of arguments for the ata_taskfile() function. This helps to
wipe quite a lot of code out as well.
This stage is not sensitive, so let's make a patch before we start to integrate
the last work of Jens Axboe.
<[email protected]> (02/04/10 1.462)
[PATCH] 2.5.8-pre3 IDE 31
- Integrate the TCQ stuff from Jens Axboe. Deal with the conflicts, apply some
cosmetic changes. We are still not at a stage where we could immediately
integrate ata_request and ata_taskfile but we are no longer far away.
- Clean up the data transfer function in ide-disk to use ata_request structures
directly.
- Kill useless leading version information in ide-disk.c
- Replace the ATA_AR_INIT macro with inline ata_ar_init() function.
- Replace IDE_CLEAR_TAG with ata_clear_tag().
- Replace IDE_SET_TAG with ata_set_tag().
- Kill georgeous ide_dmafunc_verbose().
- Fix typo in ide_enable_queued() (ide-tcq.c!)
Apparently there still problems with a TCQ enabled device and a not enabled
device on the same channel, but let's first synchronize up with Jens.
<[email protected]> (02/04/10 1.463)
[PATCH] ReiserFS directory atime fix

readdir(). Patch is written by Chris Mason.
<[email protected]> (02/04/10 1.464)
[PATCH] ReiserFS endianness fix
This patch is to fix a lookup problem on bigendian platforms
<[email protected]> (02/04/10 1.465)
[PATCH] ReiserFS get_block fix
This patch is to convert pap14030 panic into warning. While doing this,
a bug was uncovered, that when get_block() returns a failure, buffer
is still marked as mapped, and on subsequent access to this buffer
get_block() was not called anymore. This is also fixed.
<[email protected]> (02/04/10 1.466)
[PATCH] ReiserFS inode initialization
This patch is to fix a case where flag was not set at inode-read time which
prevented 32bit uid/gid to work correctly.
<[email protected]> (02/04/10 1.467)
[PATCH] fix ReiserFS metadata journalling
This patch is to add forgotten metadata journaling for a case when
we free blocks after tail conversion failures. Found and fixed by Chris Mason
<[email protected]> (02/04/10 1.468)

This patch solves a problem where separate journal device was not freed
if journal initialisation failed
<[email protected]> (02/04/10 1.469)
[PATCH] ReiserFS journal replay
This patch is to fix journal replay bug where old code would replay
transactions with mount_id != mount_id recorded in journal header.
Fixed by Chris Mason.
<[email protected]> (02/04/10 1.470)
[PATCH] ReiserFS debug config rename
This patch renames reiserfs debugging option in config output,
to make its meaning more clear.
<[email protected]> (02/04/10 1.471)
[PATCH] ReiserFS config comment clarification
This patch is to change comment of CONFIG_REISERFS_PROC_INFO config item,
to make it more clear.
<[email protected]> (02/04/10 1.472)
[PATCH] ReiserFS unconfuse
This patch removes confusing warning about journal replay on readonly FS
<[email protected]> (02/04/10 1.473)
[PATCH] ReiserFS makefile cleanup
This patch removes one tail_conversion object out of build list,
because it was specified twice. (noticed by Jeff Garzik)
<[email protected]> (02/04/10 1.474)
[PATCH] ReiserFS inode cleanup
This patch fixes a problem that was created during inode structure
cleanup/ private parts separation. This fix was made by Chris Mason.
This is very critical bugfix. Without it, filesystem corruption
happens on savelinks processing and possibly in some other cases.
<[email protected]> (02/04/10 1.475)
[PATCH] ReiserFS typo fix
This patch fixes small typo in ikernel informational message.
<[email protected]> (02/04/10 1.481)
Don't just initialize the acpi tables, use them.
<[email protected]> (02/04/11 1.482)
Don't stomp on old ia_valid when changing user/group.
Found by Andrew Morton <[email protected]>
<[email protected]> (02/04/11 1.483)
[PATCH] crapectomy in include/linux/nfsd/syscall.h
Removes an atavism in declaration of sys_nfsservctl() - sorry, I should've
remove that junk when cond_syscall() thing was done.
<[email protected]> (02/04/12 1.484)
Update defconfig for IDE TCQ configs
<[email protected]> (02/04/12 1.485)
[PATCH] qla1280.c update
Included is the latest version of the code. Indenting it properly
actually reduced the size of the files by another 10K or so.
<[email protected]> (02/04/12 1.486)
Kernel version update
<[email protected]> (02/04/12 1.487)
[PATCH] 2.5.8-pre3 IDE 32
- Don't provide symbolic links in /proc/ide - they are redundant data.
- Try to use a more reasonable default capacity value in ata_capacity().
- Fix ata_put() ata_get() usage in ide_check_media_change().
- Small readability fixes to the option parsing code.
- Apply Vojtech Pavliks /proc PIIX output fix.
- Replace all occurrences of ide_wait_taskfile() with ide_raw_taskfile(). One
duplicated code path fewer.
<[email protected]> (02/04/14 1.488)
[PATCH] 2.5.8-pre3 IDE 33
- Kill unneded parameters to ide_cmd_ioctl() and ide_task_ioctl().
- Apply Petr Vendrovecs fix for 32bit ver 16bit transfers.
- Make CD-ROM usable again by guarding the generic routines against request
field abuse found there. We will try to convert this driver to the just to be
finished struct ata_request after the generic changes stabilize a bit.
The strcut ata_taskfile and struct ata_request merge to be more preciese.
<[email protected]> (02/04/14 1.489)
[PATCH] cpqfc.o
This makes the cpqfc driver recognize the HP Tachyon. I moved the
device list to an __initdata structure so the driver doesn't build it at
runtime and changed it to use the proper PCI_DEVICE_ID_* names.
With this patch applied, the driver happily detects the disks attached
to my HP Tachyon.

[PATCH] uhci.c SMP deadlock
This patch fixes a bug reported by Greg and David, as well as some other
people recently.
uhci.c would call wait_ms, which can sleep, with spinlocks held. There
are two places where this happens, but only one was the cause of the
problem.
<[email protected]> (02/04/08 1.369.105.4)
[PATCH] uhci.c cleanup
This patch merely cleans up the code a little and doesn't fix any bugs.
It makes a couple of code paths a bit easier to understand, removes an
unused variable (uhci_list) and some procfs variables when not using
procfs.
<[email protected]> (02/04/08 1.369.105.5)
[PATCH] uhci.c incorrect locking
This fixes a problem that I've not run into and is difficult to trigger,
but definately a bug. We locked urb->lock, when we meant u->lock. It also
cleans up the code a little to make it easier to understand and removes
an obsolete comment.

[PATCH] uhci.c FSBR speed problem
The dangers of not ensuring important fields are properly set.
Some, if not all, of the speed problems with uhci.c were caused because
some important fields were not set and as a result, FSBR was never
turned on.
This patch also ensures is_suspended is set to 0 properly. This could
cause some problems suspending the HC when no devices are plugged in.

[PATCH] page limit on bulk transfers in usbfs?

[PATCH] usbfs disconnect
This was originally created by David many months ago and posted to the
list, but not put into the kernel.
I modified the original patch to:
-patch against the 2.5.7 kernel
-use the 'real' interface number, not position (to do this I added 2
methods in usb.c)

[PATCH] fix busy loop in migration thread init
Since we do not set the task state to TASK_INTERRUPTIBLE, we busy loop.
On larger SMP this can actually result in a lockup due to the way
migration thread initalisation is done (nr_cpus threads are created
and they all busy loop until the scheduler evenly distributes them,
one on each cpu. With this rogue thread busy looping things can become
unbalanced and the migration threads never distribute themselves onto
all cpus).

[PATCH] increase dynamic proc entries for ppc64
Unfortunately the proc filesystem has a limit on the number of dynamic

USB kerneldoc fixes
This fixes some kerneldoc bugs for USB. It catches up with
the recent rename, and includes a couple minor tweaks/fixes
I happened to notice.
<[email protected]> (02/04/08 1.369.105.12)
This patch is a more complete fix for the device refcount
sanity checking and cleanup on device disconnect.
- Splits apart usb_dec_dev_use(), for driver use, and
usb_free_dev(), for hub/hcd use. Both now have
kerneldoc, and will BUG() if the refcount and the
device tree get out of sync. (Except for cleanup of
root hub init errors, refcount must go to zero only
at the instant disconnect processing completes.)
- More usbcore-internal function declarations are
now moved out of <linux/usb.h> into hcd.h
- Driver-accessible refcounting is now inlined; minor
code shrinkage, it's using atomic inc/dec instructions
not function calls.
<note from greg k-h, there is still some work to be done with USB device
reference counting, but this patch is a step in the right direction.>

[PATCH] open_namei cleanup, nfsctl permission check fix
a) part of open_namei() done after we'd found vfsmount/dentry of
the object we want to open had been split into a helper - may_open().
b) do_open() in fs/nfsctl.c didn't do any permission checks on
the nfsd file it was opening - sudden idiocy attack on my part (I missed
the fact that dentry_open() doesn't do permission checks - open_namei()
does). Fixed by adding obvious may_open() calls.

I've added support for 64-bit modulo arithmetic on ARM. This is needed for

this.

2.4.18-rmk3 fails to build on the EBSA285 if there is no video stuff

mach-footbridge/arch.c ; the symbol is screen_info which is what the
ORIG_* macros use.

<[email protected]> (02/04/04 1.369.97.1)
This fixes the "i_blocks went wrong when the disk filled up"
problem.
In ext3_new_block() we increment i_blocks early, so the
quota operation can be performed outside lock_super().
But if the block allocation ends up failing, we forget to
undo the allocation.
This is not a serious bug, and probably does not warrant
an upgrade for production machines. Its effects are:
1) errors are generated from e2fsck and
2) users could appear to be over quota when they really aren't.
The patch undoes the accounting operation if the allocation
ends up failing.

Andrew Morton's ext2 sync mount speedup. Description:
At present, when mounted synchronously or with `chattr +S' in effect,
ext2 syncs the indirect blocks for every new block when extending a
file.
This is not necessary, because a sync is performed on the way out of
generic_file_write(). This will pick up all necessary data from
inode->i_dirty_buffers and inode->i_dirty_data_buffers, and is
sufficient.
The patch removes all the syncing of indirect blocks.
On a non-write-caching scsi disk, an untar of the util-linux tarball
runs three times faster. Writing a 100 megabyte file in one megabyte
chunks speeds up ten times.
The patch also removes the intermediate indirect block syncing on the
truncate() path. Instead, we sync the indirects at a single place, via
inode->i_dirty_buffers. This not only means that the writes (may)
cluster better. It means that we perform much, much less actual I/O
during truncate, because most or all of the indirects will no longer be
needed for the file, and will be invalidated.
fsync() and msync() still work correctly. One side effect of this
patch is that VM-initiated writepage() against a file hole will no
longer block on writeout of indirect blocks. This is good.
<[email protected]> (02/04/04 1.369.97.3)
ext3 filesystem sync mount speedup:
Again, we don't need to sync indirects as we dirty them because
we run a commit if IS_SYNC(inode) prior to returning to the
caller of write(2).
Writing a 10 meg file in 0.1 meg chunks is sped up by, err,
a factor of fifty. That's a best case.

[PATCH] kjournald exits with nonzero preempt_count
The preempt_count debug check that went into 2.5.8-pre1 already caught a
simple case in kjournald. Specifically, kjournald does not drop the BKL
when it exits as it knows schedule will do so for it.
For the sake of clarity and exiting with a preempt_count of zero, the
attached patch explicitly calls unlock_kernel when kjournald is exiting.

[PATCH] preemptive kernel behavior change: don't be rude
- do not manually set task->state
- instead, in preempt_schedule, set a flag in preempt_count that
denotes that this task is entering schedule off a kernel preemption.
- use this flag in schedule to jump to pick_next_task
- in preempt_schedule, upon return from schedule, unset the flag
- have entry.S just call preempt_schedule and not duplicate this work,
as Linus suggested. I agree. Note this makes debugging easier as
we keep a single point of entry for kernel preemptions.
The result: we can safely preempt non-TASK_RUNNING tasks. If one is
preempted, we can safely survive schedule because we won't handle the
special casing of non-TASK_RUNNING at the top of schedule. Thus other
tasks can run as desired and our non-TASK_RUNNING task will eventually
be rescheduled, in its original state, and complete happily.
This is the behavior we have in the 2.4 patches and 2.5 until
~2.5.6-pre. This works. It requires no other changes elsewhere (it
actually removes some special-casing Ingo did in the signal code).
