[GIT PULL] cgroup fixes for v3.10-rc4

[Tejun Heo]

Hello, Linus.

This pull request contains

* Fix for yet another xattr bug which may lead to NULL deref.

* A subtle bug in for_each_descendant_pre().  This bug requires quite
  specific conditions to trigger and isn't too likely to actually
  happen in the wild, but maybe that just makes it that much more
  nastier.

* A warning message added for silly cgroup re-mount (not -o remount,
  but unmount followed by mount) behavior.

The changes are available in the following git branch
