Hello, Linus.
One late fix for cgroup. I was waiting for another set of fixes for a
long-standing obscure cpuset bug but am not sure whether they'll be
ready before v3.17 release. This one is a simple fix for a mutex
unlock balance bug, which is detected by coccinelle and probably won't
trigger in the wild, introduced during this devel cycle.
Thanks.

It was introduced in 3.14, and it was detected by my eyes, not coccinelle. ;)

Hah, I got it completely mixed up with another patch in my head. Will
post an updated pull request. My apologies.
Thanks.

One late fix for cgroup. I was waiting for another set of fixes for a

unlock balance bug in an allocation failure path in
