What are the chances of getting this reviewed for this merge cycle?  Is
it on somebody's list?

If it would make it any simpler: the one that I think absolutely must get wider
review, and get merged through Al's tree, is "vfs: take i_mutex on renamed
file".

There aren't actually any dependencies between that and the rest; and
the rest is mainly in nfsd/ and locks.c (changes to which have mostly
been going through my tree anyway, I think); other than that:

 fs/attr.c           |    3 ++
 fs/namei.c          |   18 +++++++++++++-

straightforward changes that tend to look like:

	+	error = break_deleg(inode, O_WRONLY);
	+	if (error)
	+		return error;

 include/linux/fs.h  |   19 +++++++++++++--

and some definitions.
