Linus Torvalds: Linux-2.5.4-pre1 - bitkeeper testing

Subject: linux-2.5.4-pre1 - bitkeeper testing
Date: 05 Feb 2002 19:37:41 -0800
Ok, I've spent about a week trying to change my working habits and
scripting bitkeeper enough to (a) import a good revision controlled tree
into it from the 2.4.x and 2.5.x patch-archives and (b) try to actually
accept patches directly into bitkeeper.
Quite frankly, so far it has definitely made me slower - it took me
basically a week to get about 50 patches applied, but most of that time
by far was writing scripts and just getting used to the thing. Thanks to
Larry and Wayne for helping out with the problems I had.
And I'm not even done yet. I expect to be a bit slower to react to patches
for a while yet, until the scripts are better.
However, some of it pays off already. Basically, I'm aiming to be able to
accept patches directly from email, with the comments in the email going
into the revision control history. For a first example, the ChangeLog file
for 2.5.4-pre1 is rather more detailed than usual (in fact, right now it
is _too_ detailed, and I haven't written the scripts to "terse it down"
for postings to linux-kernel, for example).
The long-range plan, and the real payoff, comes if main developers start
using bk too, which should make syncing a lot easier. That will take some
time, I suspect.

The patch moves:
* joystick drivers from drivers/char/joystick to drivers/input/joystick
* gameport drivers from drivers/char/joystick to drivers/input/gameport
* serio drivers from drivers/char/joystick to drivers/input/serio
I don't think the joystick drivers should stay in char, because they're
NOT character device drivers (check for register_chrdev, none to be found).
It also fixes build problems with sound driver gameport support.

[PATCH] 2.5.3 ISDN work around buggy hw
the appended patch works around a bug in the PLX9050 chip. This chip is
used in various PCI ISDN adapters (it's an PCI interface chip) and has
an erratum when the BAR 0/1 has bit 7 set (the size of the region is
0x80, so aligning it to 0x80 is legal and really happens for people).
This workaround has been tested by a user who hit this problem with a
Gazel card. Basically the same fix has been done for Elsa cards, but it's

[PATCH] Drop reliance on file->f_dentry in NFS reads/writes
Following a request by David Chow on linux fsdevel, this patch causes
NFS read and write requests to take the inode from page->mapping->host
rather than relying on file->f_dentry->d_inode. Apparently this will
simplify some work he is doing on another filesystem.
In any case, it cleans up the current mix of sometimes doing one
thing, sometimes the other (historical cruft), and puts NFS client
behaviour on par with what is done in other filesystems...

[PATCH] Fix spurious ETXTBSY errors due to late release of struct file
The following patch should fix a problem of ETXTBSY sometimes
occurring if one tries to run a file straight after compilation.
The problem is that both NFS read and write requests can currently
hold a count on the struct file. This is done partly so as to be able
to pass along the RPC credential (which is cached in the struct file),
and partly so that asynchronous writes can report any errors via the
The problem is that both the read and write requests may persist even
after file close() occurs. For O_RDONLY files, this is not a problem,
but for O_WRONLY, and O_RDWR files, the fact that the struct file is
not released until the last call to nfs_release_request() means that
inode->i_writecount does not necessarily get cleared upon file
The following patch fixes both these issues.
- NFS read requests no longer hold the struct file. They take a
count on the the RPC credential itself.
- NFS write requests still hold the struct file, since they want to
report errors to sys_close() using the file->f_error mechanism.
However they are made to release the page, credential, and file
structures as soon as the write is completed instead of following
the current practice of waiting for the last nfs_page request

[PATCH] NFS lookup code rewrite w/o open(".") fix...
This is a resend of the NFS lookup code rewrite, but with the open(".")
VFS fix removed. (I'll resend the 'uses d_revalidate()' version
separately after a suitable delay to allow for comments.)
Issues fixed by this patch:
- Use the directory mtime in order to give us a hint when we should
check for namespace changes.
- Add support for the 'nocto' flag, in order to turn off the strict
attribute cache revalidation on file open().
- Simplify inode lookup. Don't check the 'fsid' field (which appears
to be buggy in too many servers in order to be reliable). Instead
we only rely on the inode number (a.k.a. 'fileid') and the
(supposedly unique) filehandle.

- Adds a 'name' file which exports just the device name
- Reduces the 'status' file to just export the bus ID. (This will change,
since the bus ID is obvious based on what directory you're in, but it's
another patch at another time)

[PATCH] nbd in 2.5.3 does not work, and can cause severe damage when read-write
I've got strange idea and tried to build diskless machine around
2.5.3... Besides problem with segfaulting crc32 (it is initialized after
net/ipv4/ipconfig.c due to lib/lib.a being a library... I had to hardcode
lib/crc32.o before --start-group in main Makefile, but it is another
story) there is bad problem with NBD caused by BIO changes:
(1) request flags were immediately put into on-wire request format.
In the past, we had 0=READ, !0=WRITE. Now only REQ_RW bit determines
direction. As nbd-server from nbd distribution package treats any
non-zero value as write, it performs writes instead of read. Fortunately
it will die due to other consistency checks on incoming request, but...
(2) nbd servers handle only up to 10240 byte requests. So setting max_sectors
to 20 is needed, as otherwise nbd server commits suicide. Maximum request size
should be handshaked during nbd initialization, but currently just use
hardwired 20 sectors, so it will behave like it did in the past.
