Summary of changes from v2.5.4-pre5 to v2.5.4-pre6
============================================
<rml@tech9.net>:
[PATCH] preemptible kernel documentation, etc
Linus,
The attached patch adds a Documentation/preempt-locking.txt file which
describes the new locking rules wrt preemptive kernels (ie, watch
per-CPU data, etc). It also updates a CREDITS entry and adds some
comments.
Patch is against 2.5.4-pre5, please apply.

TAG: v2.5.4-pre6
<rml@tech9.net>:
[PATCH] yet another lseek fix
Another lseek fix, spotted by Dave Hansen @ IBM. Missing a
corresponding lock_kernel for an unlock_kernel. Patch against
2.5.4-pre5, please apply. Thanks,
Robert Love
<kai@vaio.(none)>:
Link ISDN after USB. Otherwise, when builtin, the ST5481 USB ISDN
adapter driver initializes before the USB layer -> Oops
<kai@vaio.(none)>:
rename built-in ISDN object to vmlinux-obj.o
(was isdn.a before, but there's no need to use an archive here)
<kai@vaio.(none)>:
add missing "\n" in printk statements.
<kai@vaio.(none)>:
remove CONFIG_ISDN entries from arch/Config.help - The real entry is
in drivers/isdn/Config.help
<viro@math.psu.edu>:
[PATCH] ->s_id cleanups
Patch converts a bunch of places that hadn't been caught when
->s_id was introduced. Please, apply.
<viro@math.psu.edu>:
[PATCH] affs cleanup
affs digs in blk_size[] to find the size of device (it
has its analog of superblock living in the middle of disk). That
information is available in ->s_bdev->bd_inode->i_size - no need
to mess with major/minor/arrays to get it.
<viro@math.psu.edu>:
[PATCH] /proc/modules cleanup (seq_file, again)
/proc/modules switched to use of seq_file, cleaned up.
<viro@math.psu.edu>:
[PATCH] /proc/slabinfo cleanup (seq_...)
Straightforward rewrite to seq_file.
<viro@math.psu.edu>:
[PATCH] fix for typo in ext2_new_inode()
Please, apply. Otherwise we eat quota like there's no tomorrow ;-/
<petero2@telia.com>:
[PATCH] Make cardbus device_register work
It compiles in -pre5 but doesn't work unless you also apply the patch
below. Without this patch, bus_id will be empty which makes
device_register fail.
<jejb@mulgrave.(none)>:
Various bugfixes to sync with 2.4 version:
- Fix bug in scripts that was causing CDRW hang
- add sense buffer length initialisation
- update lasi700 to new driver model and fix rmmod hang
- add correct MCA reporting to D700 driver

[PATCH] 2.5.4pre5 scsi/aha1542.c & DMA changes
There are a couple of errors in the DMA changes to the
aha1542.c driver that appeared in 2.5.4pre3:
- a typo (BUF vs BUS)
- a macro handed a page instead of a scatterlist
- printk format length mismatch
Paul.
<torvalds@home.transmeta.com>:
Make AGP on x86 work temporarily while waiting for the proper fix.
<viro@math.psu.edu>:
[PATCH] driverfs - preparation to fixes
Make dentry and ->i_sem manipulations in driverfs explicit. Something
is seriously rotten there and real fixes will take non-trivial work
(e.g, I suspect that we actually ought to kill driverfs_rename() - at
least cross-directory one for regular files, maybe completely). This
patch simply cleans the ground.
<viro@math.psu.edu>:
[PATCH] fs/ext2/balloc.c cleanup
Mostly cosmetical cleanup - sane variable names, etc.
That's pretty much it for balloc.c cleanups - stuff after that
will be about decent threading.
<viro@math.psu.edu>:
[PATCH] ext2_new_block() cleanup
in ext2_new_block() inode->i_sb can't be NULL. Dead code removed.
merged returns in ext2_new_block()
in ext2_new_block() added a local variable (sbi) for sb->u.ext2_sb;
users converted.
calculation of prealloc_goal moved into beginning of function.
new local variable (block). Initialized to 0, set to the number of
allocated block only when we are known to be successful.
ext2_new_block() returns the value of 'block' now. As the result, out:
is gone - it's identical to out_unlock now.
check for block being chosen past the end of disk had been moved up No
sense to check that after we had done the preallocations...
quota allocation taken into the beginning of ext2_new_block(). we put
the number of blocks we'd reserved into dq_alloc and then decrement it
each time old code would do DQUOT_ALLOC/increment when it would do
DQUOT_FREE. On the exit we release dq_alloc blocks I.e. all
allocations are pushed into the beginning and all freeing - to the end.
now that we had moved the last possible point of failure up, we can do
the same with assignment of final result to block.
code that does allocation within a group had been taken out into a
helper - grab_block(map, size, goal).
decrementing fs-wide free blocks count moved into the beginning of
function. We try to reserve up to dq_alloc blocks - amount we _can_
grab is limited by the actual free space and root-reserved percentage.
That logics had been taken into a helper - reserve_blocks(sb, amount).
Number of blocks we had managed to reserve is put into es_alloc. When
we actually grab a block, es_alloc is decremented. Upon the exit we
release the leftovers. Old code didn't honor 'reserved for root' limit
when doing prealloc - now that had been fixed.
EXT2_BLOCKS_PER_GROUP(sb) put into a local variable (group_size)
similar "reserve and release leftovers in the end" scheme for group
(i.e. we try to reserve as much as we want in the group, then count how
much had been used up and release the leftovers in the end).
cleaned up the preallocation loop.
<viro@math.psu.edu>:
[PATCH] (5/5) ext2_free_blocks() cleanup
minor cleanup: update 'freed' only after we finish with group
<viro@math.psu.edu>:
[PATCH] (4/5) ext2_free_blocks() cleanup
in ext2_free_blocks() inode->i_sb can't be NULL; dead code removed.
<viro@math.psu.edu>:
[PATCH] (3/5) ext2_free_blocks() cleanup
new helper - group_release_blocks(desc, bh, count); updates free blocks
count for given group ext2_free_blocks now counts the blocks freed in
group and updates the per-group free blocks count at once.
<viro@math.psu.edu>:
[PATCH] (2/5) ext2_free_blocks() cleanup
we postpone releasing the quota until the end of ext2_free_blocks() and
do that at once.
<viro@math.psu.edu>:
[PATCH] (1/5) ext2_free_blocks() cleanup
new helper function - release_blocks(sb, n); in ext2_free_blocks() we
count the blocks we'd freed and update the fs-wide count of free blocks
in the end - just before unlocking superblock. instead of doing that
step at a time.

[PATCH] Re: [PATCH] Preemptible Kernel for 2.5
On Sat, 2002-02-09 at 01:43, Linus Torvalds wrote:
> That will clean up all your issues with header file ordering.
You are right, it did. I removed all the sched.h dependencies and this
reduced the size of the patch greatly. I now use current_thread_info()
and none of the header or include hackery from before. I've tested this
with and without preemption enabled with success.
I appreciate your help with this.
Again, this is a minimal i386-only patch. I have other arches,
documentation, etc. Patch against 2.5.4-pre5. Enjoy,
Robert Love
<jgarzik@rum.normnet.org>:
Add pci ids found in 2.4.18-pre9's version of eepro100 net driver
to the current driver.
<jgarzik@rum.normnet.org>:
Update eepro100 net driver pci id list, at the prompting of
Andrew Morton and Hanno Boeck.
Three constants are substituted with their numeric equivalents,
a reverse of the norm, to make the linear progression of PCI ids
more clear, and easier to validate at a glance.
Summary of changes from v2.5.4-pre4 to v2.5.4-pre5

exp_procfs_exports() switched to seq_..., missing lock added.
<viro@math.psu.edu>:

unneeded these days..
<davej@suse.de>:
[PATCH] Config.in updates
- Reorder mainmenu items so CONFIG_EXPERIMENTAL is at the top again.
- Various updates from 2.4
<davej@suse.de>:
[PATCH] Power management support for opl3sa2 driver
<davej@suse.de>:
[PATCH] fix serial close hang
2.4/2.5 kernels suffer from an infinitely long hang when a serial tty device
is closed, and there are characters waiting to be sent. The hang occurs in
tty_wait_until_sent.
There is a timeout 'closing_wait' which defines how long to wait for the TX
buffers to empty; the problem is that the serial layer totally ignores it.
It is stored in two structures, 'info' and 'state'. It is initialised in
the 'state' structure, but used from the 'info' structure.
It turns out that 'hub6' was also missing.
I'm not currently clear what the expected behaviour should be when the
timeout is changed via setserial, and others have the port open - I've
opted to preserve the timeout until all users close the port. It's
trivial to change this behaviour though.
<davej@suse.de>:
[PATCH] AGPGart update
Mostly from 2.4.17 / 18pre.
- Code cleanup
- Fix suspend/resume on several chipsets
- Add support for i820.
<davej@suse.de>:
[PATCH] text.lock -> subsection changes.
Make spinlocks etc use subsections of their parent sections instead of
an ELF section of their own - needed for newer binutils when the parent
sector is removed.
<davej@suse.de>:
[PATCH] handle out of spec SMP athlons.
Newer Athlons have means of checking if they are SMP capable or not.
This code adds checks that printk a warning on systems not intended
for SMP, and set the taint flag that modutils is already aware of.
The taint code is also improved to use defines instead of magic numbers.
<greg@soap.kroah.net>:
typo fix for the name of the pci hotplug filesystem caused by the superblock changes.

new helper - exp_get_by_name(client, vfsmount, dentry). Used
in places where we travers mountpoint.
<viro@math.psu.edu>:

Update eepro100 net driver link state tracking:
* Initialize interface carrier state in speedo_open.
* Update previous netif_carrier_{on,off} change to use
linux/mii.h constants.
Contributor: Andrew Morton, with modifications from me
<jgarzik@rum.normnet.org>:
Fix natsemi net driver rx-related hang, by polling for RX events
on all RX interrupts. Prior to this fix, RX FIFO overrun and RX
buffer overrun interrupts did not trigger an RX poll; now they do.
Contributor: Manfred Spraul
<jgarzik@rum.normnet.org>:
Update tulip net driver to indicate link beat to system,
via netif_carrier_{on,off}. Some placeholders to do this were
already in the code, making this an even easier and more obvious patch.
Also, decrease time until next link beat check, if link beat
is not present. (previously the code would wait 60 seconds until
next check, regardless of current link state)
Contributor: Stefan Rompf, with changes from me
<jgarzik@rum.normnet.org>:
tulip net driver updates:
* Add support for Conexant tulip clones.
* Do not store eeprom data on stack (128 or 512 bytes), it's a
large object, and also, we already have a copy in kmalloc'd RAM.
Contributor: Pavel Roskin
<jgarzik@rum.normnet.org>:
Fix naming conflict with pcnet32 net driver and ethtool,
by cleaning up the pcnet32 namespace a bit.
s/PORT_/PCNET32_PORT_/ for local constants, to avoid conflicting
with linux/ethtool.h.
Contributor: William Lee Irwin III
<jgarzik@rum.normnet.org>:
Add config option to enable natsemi net driver hardware bug workaround.
"some" systems with "some" cables see a large amount of errors,
due to a hardware bug. This bug is (apparently) not probe-able;
however it only appears on rare reference boards and the like,
so we simply add a config option and default the option to OFF.
Further detail:
When CONFIG_NATSEMI_CABLE_MAGIC option is enabled, PMDCSR_VAL
register value becomes 0x1898, a value provided by a NatSemi
app note. This enables a workaround for a hardware bug
which is (apparently) not probe-able. Luckily the hardware bug
is (apparently) not common either, so we default to disabling
this workaround.

<jgarzik@rum.normnet.org>:
Fix typo in the winbond-840 net driver which doubled
the size of the Tx data buffer list without cause.
Spotted by Dave Jones.
<jgarzik@rum.normnet.org>:
After Al Viro's recent swapfile cleanup, the swap_device member of
swap_info_struct became pretty much superfluous. As we are minimizing
kdev_t usage anyway, I took the opportunity to remove swap_device
member, and replace the remaining usages with SWP_BLOCKDEV bit flag.
Adding SWP_BLOCKDEV in turn motivated a small cleanup of the
SWP_xxx bit flags and their usage.
Patch has been in light testing for a couple weeks, and
has been glanced at by Al. "looks sane"
<torvalds@penguin.transmeta.com>:

<dhowells@redhat.com>:
[PATCH] thread information block
The first fix changes get_wchan() and the second one fixed what DaveM noticed.
<rml@tech9.net>:
[PATCH] another llseek change fix
Fixe another typo in the recent llseek cleanups. Typo was spotted by
Miloslav Trmac ... hopefully the last.
<viro@math.psu.edu>:
[PATCH] the rest of ->get_sb() switchover
Switch over ext3, ufs, reiserfs, msdos, vfat, isofs, qnx4, hpfs, efs,
udf, romfs, bfs, affs, hfs, adfs, cramfs, ntfs, jffs, jffs2 and freevxfs
to new ->get_sb().
Kill ->read_super() that is thus no longer used.
<jgarzik@rum.normnet.org>:
eepro100 net driver link beat detection improvement.
Control interface running flag correctly, via netif_carrier_{on,off},
rather than manipulating the IFF_RUNNING bit directly from within
the driver (ug).

============================================
<torvalds@penguin.transmeta.com>:
update version
TAG: v2.5.4-pre3
<dhowells@redhat.com>:
[PATCH] thread information block
syscall latency improvement
* There's now an asm/thread_info.h header file with the basic structure
def and asm offsets in it.
* There's now a linux/thread_info.h header file which includes the asm
version and wraps some bitops calls to make convenience functions for
accessing the low-level flags.
* The task_struct has had some fields removed (and some flags), and has
acquired a pointer to the thread_info struct.
* task_struct's are now allocated on slabs in kernel/fork.c, whereas
thread_info structs are allocated at the bottom of the stack pages.
* Some more convenience functions are provided at the end of linux/sched.h to
access flags in other tasks (these are here because they need to access the
task_struct).
<greg@soap.kroah.net>:
Added driverfs support for the USB subsystem.

[PATCH] tkill ia64 syscall table entry
minor nit, but it seems the tkill() patch added a sys_tkill entry without

<Matt_Domsch@dell.com>:
[PATCH] BLKGETSIZE64 (bytes not sectors)
Linus, below is a patch to return the size of a device in bytes, not
in units of 512-byte sectors (which is incorrect per function

[PATCH] Input drivers, step #3
This patch updates the input core to the current version, fixing a bunch
of bugs, adding hotplug support and a listing of available input devices
in /proc. The later is very useful for troubleshooting.

[PATCH] Fix mount hash table
On my 512MB machine with 6 mount points the mount hash table uses 64K.
This patch brings it to a more reasonable size by limiting it to one
page.
<ak@muc.de>:
[PATCH] Fix page cache limit wrapping in filesystems
Several file systems in tree that nominally support files >2GB set their
s_maxbytes value to ~0ULL. This has the nasty side effect on 32bit machines
that when a file write reaches the page cache limit (e.g. 2^43) it'll silently
wrap and destroy data at the beginning of the file.
This patch changes the file systems in question to fill in a proper limit.
I also have an alternate patch that adds a check for this generically
in super.c, but preliminary comments from Al suggested that he prefered
to do it in the file systems, so it is done this way way.

[PATCH] Automatic file-max sizing

patch does dynamic sizing for it instead. It assumes file+inode+dentry
are roughly 1K and will use upto 10% of the memory for it.
Also removes two obsolete prototypes.

[PATCH] Bootmem speedup
This patch speeds the bootmem freeing up a bit. Not particularly important,
but helps on some slow simulators where the loop can chew up significant
CPU time.

[PATCH] Slab name cleanup - last try
Hallo Linus,
This is the slab name cleanup you originally requested when the reiserfs
slab name too long boot bug was introduced. It replaces the static
name limit for slab cache names with the requirement for the caller
to supply a stable name. This version addresses all concerns that were given
over earlier versions of the patch.
As I do not feel very strongly about the slab cache name limit and you
also do not seem to be interested in it and the original bug of reiserfs
not booting anymore has been long fixed in your tree with the patch
you originally rejected from me I will not resend this patch after this
try.
Patch against 2.5.4pre1.

useless.
<viro@math.psu.edu>:
[PATCH] (3/8) ->get_sb() switchover
ext2 switched to ->get_sb(). For that we had
a) turned ext2_read_super() into ext2_fill_super() (instead of
"return NULL if failed and sb if succeeded" it's "return error value or
0").
b) added ext2_get_sb(type, flags, dev, data) - all it does is
return get_sb_bdev(type, flags, dev, data, ext2_fill_super);
c) replaced DECLARE_...() with explicit initializer.
That's it.

OK, here comes the long-promised switchover to ->get_sb().
New method added - ->get_sb(type, flags, dev, data). At this point we
still keep ->read_super(), but it will go away in the end of series.
->get_sb() is a generalization of get_sb_{bdev,nodev,single}() - as the
matter of fact, these will become common helpers used by filesystems in
their ->get_sb().

[PATCH] 2.5.4-pre1: further llseek cleanup (3/3)
The previous patch did not provide protection for device lseek methods
(drivers/* stuff). This patch pushes the BKL into each of the remaining
lseek methods -- without them we have a race.
I'd much prefer to have a a better lock to push down than the BKL, but
that will have to wait.
Before you balk at the size, remember patch #2 in this series which
removed much code ;-)
Thanks to Al for assistance, especially a listing of affected files.

[PATCH] 2.5.4-pre1: further llseek cleanup (2/3)
This is the second patch of three implementing further llseek cleanups,
against 2.5.4-pre1. It does not depend on the other patches.
This patch cleans up various code and quite nicely removes much more
code than it adds. Specifically:
- remove static lseek method which merely reimplements
the standard no_llseek in the following seven files:
hci_vhci.c, ite8172.c, nec_vrc5477.c, auerswald.c,
pipe.c, netlink_dev.c, and socket.c
- remove fs/ufs/file.c::ufs_file_lseek -- Al says it is
reimplementing generic_file_llseek, so let's use that
instead (the comment about 32-bit sizes shouldn't be
an issue, the generic method checks size)
- include smp_lock.h in 3 files missed from previous
'remove bkl' patch
- Documentation/filesystem/Locking update
Please, apply.

<rml@tech9.net>:
[PATCH] 2.5.4-pre1: further llseek cleanup (1/3)
This is the first of three patches implementing further llseek cleanup,
against 2.5.4-pre1.
The 'push locking into llseek methods' patch was integrated into 2.5.3.
The networking filesystems, however, do not protect i_size and can not
rely on the inode semaphore used in generic_file_llseek.
This patch implements a remote_llseek method, which is basically the
pre-2.5.3 version of generic_file_llseek. Locking is done via the BKL.
When we have a saner locking system in place, we can push it into this
function in lieu.
Ncpfs, nfs, and smbfs have been converted to use this new llseek.
Note this is updated over the previous posted patch.

[PATCH] Third version of signal changes for thread groups
During the course of developing our pthread library (the NGPT pthread
library) it became clear we needed some kernel support for handling
signals. This patch helps the library by redirecting all signals sent
to tasks in a thread group to the thread group leader. It also defines
the tkill() system call so the library can signal a specific task if
necessary.
Given that as far as I know NGPT is the only user of thread groups, and
that this change would benefit any other user of thread groups, I'm
submitting this for inclusion in the 2.5 kernel.
Note that this patch also adds support for sys_gettid() for the
architectures that don't have it. While this could have been split into a
spearate patch, it would create conflicts since this patch also adds
sys_tkill(), so I felt it was cleaner to leave them together.

[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
untested.

<trond.myklebust@fys.uio.no>:
[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...
<trond.myklebust@fys.uio.no>:
[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
file->f_error mechanism.
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
close().
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
release.
<trond.myklebust@fys.uio.no>:
[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.

[PATCH] driver model updates (5/5)

<mochel@osdl.org>:
[PATCH] driver model updates (4/5)
Patch 4: Add some default files for PCI devices.
This adds two files for PCI devices: 'irq' and 'resources'. They display
just those things and currently do nothing on write. These are the

[PATCH] driver model updates (3/5)
Patch 3: Make default callbacks simpler.
I want to move as much to a 1 file/1 value model as possible. I haven't
come up with a clean way to enforce it except via social pressure.
This patch is a step in that direction. It:
- Reduces the output of 'power' to just the decimal state of the device
- 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)
<mochel@osdl.org>:
[PATCH] driver model updates (1/5)

[PATCH] nbd in 2.5.3 does not work, and can cause severe damage when read-write
Hi Linus,
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.
