Merge branch 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup changes from Tejun Heo:
"This pull request contains the following changes.
- cgroup_subsys_state (css) reference counting has been converted to
percpu-ref. css is what each resource controller embeds into its
own control structure and perform reference count against. It may
be used in hot paths of various subsystems and is similar to module
refcnt in that aspect. For example, block-cgroup's css refcnting
was showing up a lot in Mikulaus's device-mapper scalability work
and this should alleviate it.
- cgroup subtree iterator has been updated so that RCU read lock can
be released after grabbing reference. This allows simplifying its
users which requires blocking which used to build iteration list
under RCU read lock and then traverse it outside. This pull
request contains simplification of cgroup core and device-cgroup.
A separate pull request will update cpuset.
- Fixes for various bugs including corner race conditions and RCU
usage bugs.
- A lot of cleanups and some prepartory work for the planned unified
hierarchy support."
