[PATCH v15 00/22] Richacls (Core and Ext4)

[Andreas Gruenbacher <agruenba@redhat.com>]

Here is another update to the richacl patch queue.  This posting contains
the patches ready to be merged; the patches later in the queue still need
some more review.

Changes since the last posting (http://thread.gmane.org/gmane.linux.kernel.cifs/11221):

 * Replacing an existing file or directory requires to be able to delete
   and recreate it.  A new function may_replace was added to test for replace
   access vs. delete access (may_delete); this simplifies the code and makes it
   more readable.  Without richacls, deleting and creating requires the same
   permissions, and making that distinction wasn't useful.

 * The DELETE permission on a file was accidentally allowing to replace the
   file without also requiring the ADD_FILE permission on the containing
   directory.  This was fixed and a regression test was added to the test
   suite.

 * A comment as to how pages for XDR-encoded ACLs are alocated was added to
   __nfs4_proc_set_acl.  (See the complete patch queue for that.)
