Linus, this reverts limit for request size from 10KB to unlimited.
Although no released nbd version supports it, it is certainly better to
add support to servers than cripple clients if incompatibility does
not matter.

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...

  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.

  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.

09-64bit_bitops_fix-1.diff
    Bitopts arguments must be long, not int.

08-unfinished_rebuildtree_message.diff
    Give a proper explanation if unfinished reiserfsck --rebuild-tree
    run on a fs was detected.

07-remove_nospace_warnings.diff
    Do not print scary warnings in out of free space situations.

06-return_braindamage_removal.diff
    Kill stupid code like 'goto label ; return 1;'

05-kernel-reiserfs_fs_h-offset_v2.diff
    Convert erroneous le64_to_cpu to cpu_to_le64

04-nfs_stale_inode_access.diff
    This is to fix a case where stale NFS handles are correctly detected as
    stale, but inodes assotiated with them are still valid and present in cache,
    hence there is no way to deal with files, these handles are attached to.
    Bug was found and explained by
    Anne Milicia <milicia@missioncriticallinux.com>

03-key_output_fix.diff
    Fix all the places where cpu key is attempted to be printed as ondisk key

02-prealloc_list_init.diff
    prealloc list was forgotten to be initialised.

01-pick_correct_key_version.diff
    This is to fix certain cases where items may get its keys to be interpreted
    wrong, or to be inserted into the tree in wrong order. This bug was only
    observed live on 2.5.3, though it is present in 2.4, too.

Remove struct iobus.

There is a lot of duplication between struct device and struct iobus, both
in their members and the code in their interfaces. Waxing struct iobus
removes this duplication and makes things a bit simpler.

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
examples for other subsystems to use for creating files ('Hey, look how
simple it is!')

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)

Patch 1: Make device_driver_init() an initcall.
It declares it as subsys_initcall and removes the explicit call from
init/main.c::do_basic_setup().

Here is a patch to enhance xconfig to read the new Config.help files.
Olaf Dietsche wrote this, and Steven Cole passed it on to me.

Testing: Steven Cole tested it, and I tested it.

A trivial patch that fixes this irritation in my dmesg, 2.5.3:

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.

This patch paves the way for a new driver which needs the
functionality.  Now parport_daisy_select actually _uses_ its mode
parameter.

	* drivers/parport/daisy.c: Make parport_daisy_select aware of
	its 'mode' parameter.
	* drivers/parport/ChangeLog: Updated.

This patch fixes a potential deadlock in ppdev.

	* drivers/char/ppdev.c: Watch out for errors from
	parport_claim_or_block.
	* drivers/parport/share.c: Watch out for signals.
	* drivers/parport/ChangeLog: Updated.

I finally found the reason that printer console sometimes acted up
(duh):

	* drivers/char/lp.c: Fix printer console.

This patch prevents ppdev from oopsing when the PPGETMODES ioctl is
used before a PPCLAIM.

	* drivers/char/ppdev.c: Fix an oops in PPGETMODES handling.

This patch (from 2.4.x) cleans up the use of the ECR in parport_pc.

	* drivers/parport/parport_pc.c: Integrate fixes and cleanups
	from Damian Gruszka (VScom).
	* drivers/parport/ChangeLog: Updated.

Gets sparc64 in sync with 2.5.3 final changes.

Missing smp_lock.h inclusion.

linux/malloc.h --> linux/slab.h

I made a typo the other weeks while renaming the interfaces for you,
oops.  Please apply, thanks.
