Hi,

So far I've heard no objections or seen any review suggestions. Paul if you are
OK with this patch, I'll ask Andrew to include it in -mm.

People waiting on this patch

1. Pekka Enberg for revoke* syscalls
2. Serge Hallyn for swap namespaces
3. Myself to implement the rlimit controller for cgroups
