| |
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 in an allocation failure path in pidlist_array_load(). The bug was introduced in v3.14 and the fix is tagged for -stable.
Thanks.
