Tim had started looking at it a while ago, and for a patch of this
complexity I'm more than happy to wait a long time for a throughout review.

This particular non-atomicy doesn't exist with the current code, btw
because we don't do any adjustments of the ACL entries on chmod time.

In fact we might just drop this call because XFS doesn't require the
ACL to be minimal and the other filesystems only do it for compatiblity
with future ACE entry types that will most likely never exist.  That's
why I'd like to wait for some comments from Tim - I just make sure
the latest version of the patch always stays posted for anyone to look
at it.
