[PATCH v11 00/48] Richacls

Here is another update of the richacl patch queue. I would like to ask for
feedback so that the core and local filesystem code (patches 1-24) can be
merged in the 4.4 merge window.

Changes since the last posting (http://lwn.net/Articles/660392/):

* The kernel nfs client can now distinguish between users and
groups which have no ID mapping and the nobody user/group.
This requires an extension to the nfsidmap user-space helper
from the nfs-utils package [2]. When the kernel detects
that nfsidmap doesn't support the new mapping, it falls
back to the old one.

* Minor bugs with unmapped user and group names in nfs and nfsd
have been fixed. Some functions have been split to be easier
to understand.

* The ext4 and xfs filesystem code has been simplified based on
feedback from Dave Chinner. On xfs, richacls can no longer
be compiled out (but they will only be effective on file
systems with the richacl feature set).

The complete patch queue is available in git form at [1]. The richacl
user-space utilitites and test suite are available at [3]. Please see the
richacl homepage [4] for more information.
