The regression was caused by:
commit[a32ea1e1f9] Fix read/truncate race
This causes ntfs_readpage() to be called for a zero i_size inode, which
failed when the file was compressed and non-resident.
Thanks a lot to Mike Galbraith for reporting the issue and tracking down
the commit that caused the regression.
Looking into it I found three bugs which the patch fixes.

Kernel bugzilla bug #9228
If mount helper (mount.cifs) missing, mounts with form like
//10.11.12.13/c$ would not work (only mounts with slash e.g.
//10.11.12.13\\c$ would work) due to problem with slash supposed
to be converted to backslash by the mount helper (which is not
there).
If we fail on converting an IPv4 address in in4_pton then
try to canonicalize the first slash (ie between sharename
and host ip address) if necessary. If we have to retry
to check for IPv6 address the slash is already converted
if necessary.

It's currently possible to send posix_locks_deadlock() into an infinite
loop (under the BKL).
For now, fix this just by bailing out after a few iterations. We may
want to fix this in a way that better clarifies the semantics of
deadlock detection. But that will take more time, and this minimal fix
is probably adequate for any realistic scenario, and is simple enough to
be appropriate for applying to stable kernels now.
Thanks to George Davis for reporting the problem.

I wonder on what type of UFS do you test this patch? NetBSD and FreeBSD
do not use "fs_state", they use "fs_clean" flag, only Solaris does check
like this: fs_state + fs_time == FSOK.
That's why parentheses was like that.
At now with linux-2.6.24-rc1-git1, I get: fs need fsck, but NetBSD's fsck
says that's all ok.
I suggest revert this patch.

It is not safe to to place struct pernet_operations in a special section.
We need struct pernet_operations to last until we call unregister_pernet_subsys.
Which doesn't happen until module unload.
So marking struct pernet_operations is a disaster for modules in two ways.
- We discard it before we call the exit method it points to.
- Because I keep struct pernet_operations on a linked list discarding
it for compiled in code removes elements in the middle of a linked
list and does horrible things for linked insert.
So this looks safe assuming __exit_refok is not discarded
for modules.

Commit eda3cef8dd ("NFS: Fix error
handling in nfs_direct_write_result()") ensured that if a WRITE returns
an error, then data->res.verf->committed is not tested (as it is not
initialised).
Then commit 60fa3f769f ("NFS: Fix two bugs
in the O_DIRECT write code") inadvertently reverted this while fixing
other problems.
So move the test so that we never examine ->committed in an error case,
and fix a speeling error while we are there.
