[GIT PULL] cgroup fixes for v3.7-rc2

[Tejun Heo <tj@kernel.org>]

Hello, Linus.

This pull request contains three fixes.  Two are reverts of
task_lock() removal in cgroup fork path.  The optimizations
incorrectly assumed that threadgroup_lock can protect process forks
(as opposed to thread creations) too.  Further cleanup of cgroup fork
path is scheduled.  The third fixes cgroup emptiness notification
loss.

Please pull from the following git branch to receive the above
changes.
