[RFC v4 00/31] Richacls

[Andreas Gruenbacher <andreas.gruenbacher-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hello,

here's another update of the richacl patch queue.  The changes since the last
posting (https://lwn.net/Articles/641764/) include:

* The owner and other masks now determine the owner and other
  permissions rather than just limiting them. For example, a
  'chmod u=rw' will always grant the owner read and write access.
  The group mask still behaves as before and only limits the group
  class permissions.  Hence, the owner, group, and other masks
  now behave like the 'user::', 'group::', and 'mask::' entries in
  POSIX ACLs.

* ACL entries for users matching the current owner are treated similar to
  owner@ entries; they match the file owner. This differs from how such
  entries are treated in POSIX ACLs but is more consistent with the
  NFSv4 / Windows ACL model.

* Permissions implicitly granted to the owner ("ACo") are no longer added to
  owner@ entries automatically (they are still granted though). The idea
  behind adding them was to make the acl reflect the actual permissions
  more closely, but that didn't turn out to be helpful.

* Various smaller improvements and bug fixes.

The complete patch queue is available here:

  git://git.kernel.org/pub/scm/linux/kernel/git/agruen/linux-richacl.git \
        richacl-2015-06-24

I'm leaving out patches here which have been queued for 4.2 already.  Also,
the nfs patches need some more work before another round of reviews.

Thanks,
Andreas
