[PATCHSET cgroup/for-3.8] netcls_cgroup: implement hierarchy support

[Tejun Heo <tj-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Hello, guys.

This patchset implements proper hierarchy support for netcls_cgroup.
Pretty simliar to the netprio one[3].  Simpler as each cgroup has
single config value instead of array of them.

This patchset contains the following three patches.

 0001-netcls_cgroup-introduce-netcls_mutex.patch
 0002-netcls_cgroup-introduce-cgroup_cls_state-is_local.patch
 0003-netcls_cgroup-implement-proper-hierarchy-support.patch

This patchset is on top of

cgroup/for-3.8 ef9fe980c6 ("cgroup_freezer: implement proper hierarchy support")
+ [1] "[PATCHSET cgroup/for-3.8] cgroup: allow ->post_create() to fail"
+ [2] "[PATCH 1/2] cgroup: s/CGRP_CLONE_CHILDREN/CGRP_CPUSET_CLONE_CHILDREN/"
      "[PATCH 2/2] cgroup, cpuset: remove cgroup_subsys->post_clone()"
+ [3] "[PATCHSET cgroup/for-3.8] netprio_cgroup: implement hierarchy support"

and available in the following git branch.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-netcls_cgroup-hierarchy
