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.
