[GIT PULL] cgroup changes for 3.9-rc1

[Tejun Heo]

Hello, Linus.

These are cgroup changes for 3.9-rc1.  Nothing too drastic.

* Removal of synchronize_rcu() from userland visible paths.

* Various fixes and cleanups from Li.

* cgroup_rightmost_descendant() added which will be used by cpuset
  changes (it will be a separate pull request).

The changes are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.9
