SRU Justification:
[Impact]
A race condition can occur that can be triggered when cleaning up LXC containers that use NAT/netns.
[Fix]
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=945b2b2d259d1a4364a2799e80e8ff32f8c6ee6f
[Testcase]
Using many LXC containers with NAT/netns and creating and destroying may trigger this issue.
