Subject: [PATCH 0/4] user namespace fixes
Date: Fri, 14 Dec 2012 14:01:57 -0800	[thread overview]
Message-ID: <87txroxpgq.fsf@xmission.com> (raw)


These are fixes from Andys review of my user namespace tree.

The first two patches are critical must fix fixes.

The third patch fixing commit_creds is a nice to have but fixing it
would be good.

Andy, Serge  if you could give these patches a once over to make certain
I am not doing something stupid.

Thank you,
Eric
