This patch contains the following possible cleanups:
- every function should #include the headers containing the prototypes
of it's global functions
- static functions in C files shouldn't be marked "inline", gcc should
know best when to inline
The only fields that we have to watch out for are the dentry and vfsmount.
Additionally, this makes Unionfs gentler on the stack as nameidata is rather
large.

The stale inode operations were heavily based on bad inode operations. This
patch removes stale_inode.c and converts all users of stale_inode_ops to
bad_inode_ops as there seems to be no reason to return ESTALE instead of
EIO.
This is the more appropriate than porting the bad_inode.c fix (commit

These series of patches add UFS2 write-support.
UFS2 - is default file system for recent versions of FreeBSD.
The main differences from UFS1 from write support point of view
are:
1)Not all inodes are allocated during formatation of disk.
2)All meta-data(pointer to data blocks) are 64bit(in UFS1 th

Hide some of the open-coded nr_segs tests into the iovec helpers. This is
all to simplify generic_file_buffered_write, because that gets more complex
in the next patch.

Quite a bit of code is used in maintaining these "cached pages" that are
probably pretty unlikely to get used. It would require a narrow race where
the page is inserted concurrently while this process is allocating a page
in order to create the spare page. Then a multi-page write into an uncached
p
Modify the core write() code so that it won't take a pagefault while holding a
lock on the pagecache page. There are a number of different deadlocks possible
if we try to do such a thing:
1. generic_buffered_write
2. lock_page
3.prepare_write
4. unlock_page+vmtruncate
5. copy_from_u
Allow CONFIG_DEBUG_VM to switch off the prefaulting logic, to simulate the
difficult race where the page may be unmapped before calling copy_from_user.
Makes the race much easier to hit.
This is useful for demonstration and testing purposes, but is removed in a
subsequent patch.

If prepare_write fails with AOP_TRUNCATED_PAGE, or if commit_write fails, then
we may have failed the write operation despite prepare_write having
instantiated blocks past i_size. Fix this, and consolidate the trimming into
one place.

The following set of patches attempt to fix the buffered write
locking problems (and there are a couple of peripheral patches
and cleanups there too).
Patches against 2.6.20-rc6. I was hoping that 2.6.20-rc6-mm2 would
be an easier diff with the fsaio patches gone, but the readahead
