[PATCH] nfsd: check error status from nfsd_sync_dir

Change nfsd_sync_dir to return an error if ->sync fails, and pass that error
up through the stack. This involves a number of rearrangements of error
paths, and care to distinguish between Linux -errno numbers and NFSERR
numbers.

In the 'create' routines, we continue with the 'setattr' even if a previous
sync_dir failed.

This patch is quite different from Takashi's in a few ways, but there is still
a strong lineage.

(James, I haven't touched selinux yet because it's doing various odd things
and I'm not sure how it would interact with the security attribute fallbacks
you added. Could you investigate whether it could use vfs_getxattr or if not
add a __vfs_getxattr helper to share the bits it is fine with?)

For NFSv4: instead of just converting it add an nfsd_getxattr helper for the
code shared by NFSv2/3 and NFSv4 ACLs. In fact that code isn't even
NFS-specific, but I'll wait for more users to pop up first before moving it to
common code.

[PATCH] knfsd: reduce stack consumption

A typical nfsd call trace is
nfsd -> svc_process -> nfsd_dispatch -> nfsd3_proc_write ->
nfsd_write ->nfsd_vfs_write -> vfs_writev

These add up to over 300 bytes on the stack.
Looking at each of these, I see that nfsd_write (which includes
nfsd_vfs_write) contributes 0x8c to stack usage itself!!

It turns out this is because it puts a 'struct iattr' on the stack so
it can kill suid if needed. The following patch saves about 50 bytes
off the stack in this call path.

[PATCH] knfsd: check error status from vfs_getattr and i_op->fsync

Both vfs_getattr and i_op->fsync return error statuses which nfsd was
largely ignoring. This as noticed when exporting directories using fuse.

This patch cleans up most of the offences, which involves moving the call
to vfs_getattr out of the xdr encoding routines (where it is too late to
report an error) into the main NFS procedure handling routines.

There is still a called to vfs_gettattr (related to the ACL code) where the
status is ignored, and called to nfsd_sync_dir don't check return status
either.

[PATCH] knfsd: fix setattr-on-symlink error return

This is a somewhat cosmetic fix to keep the SpecFS validation test from
complaining.

SpecFS want's to try chmod on symlinks, and ext3 and reiser (at least) return
ENOTSUPP.

Probably both sides are being silly, but it is easiest to simply make it a
non-issue and filter out chmod requests on symlinks at the nfsd level.

[PATCH] inotify

inotify is intended to correct the deficiencies of dnotify, particularly
its inability to scale and its terrible user interface:

* dnotify requires the opening of one fd per each directory
that you intend to watch. This quickly results in too many
open files and pins removable media, preventing unmount.
* dnotify is directory-based. You only learn about changes to
directories. Sure, a change to a file in a directory affects
the directory, but you are then forced to keep a cache of
stat structures.
* dnotify's interface to user-space is awful. Signals?

inotify provides a more usable, simple, powerful solution to file change
notification:

* inotify's interface is a system call that returns a fd, not SIGIO.
You get a single fd, which is select()-able.
* inotify has an event that says "the filesystem that the item
you were watching is on was unmounted."
* inotify can watch directories or files.

Inotify is currently used by Beagle (a desktop search infrastructure),
Gamin (a FAM replacement), and other projects.

See Documentation/filesystems/inotify.txt.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
