Merge branch 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
"cgroup file type addition / removal is updated so that file types are
added and removed instead of individual files so that dynamic file
type addition / removal can be implemented by cgroup and used by
controllers. blkio controller changes which will come through block
tree are dependent on this. Other changes include res_counter cleanup
and disallowing kthread / PF_THREAD_BOUND threads to be attached to
non-root cgroups.
There's a reported bug with the file type addition / removal handling
which can lead to oops on cgroup umount. The issue is being looked
into. It shouldn't cause problems for most setups and isn't a
security concern."
Fix up trivial conflict in Documentation/feature-removal-schedule.txt

There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide
similar functionality.

+----------------------------
+
+What: cgroup option updates via remount
+When: March 2013
+Why: Remount currently allows changing bound subsystems and
+ release_agent. Rebinding is hardly useful as it only works
+ when the hierarchy is empty and release_agent itself should be
+ replaced with conventional fsnotify.
