Just a short question, what happened to this patch? As far as I can
tell, 3.13rc8 doesn't include it, neither does the current 3.12.7. This
means that lxc-attach currently still doesn't work on 3.12 and probably
won't work on 3.13 either... (3.11 is fine, see the previous mails in
this thread.)

So, hm. I didn't realize it hadn't hit upstream, because it's in the
ubuntu kernel (unfortunately wrongly attributed).
However it is in linux-next since Nov 27.
