[GIT PULL] cgroup changes for v3.13-rc1

[GIT PULL] cgroup changes for v3.13-rc1

[Tejun Heo]

Hello, again.

Not too much activity this time around.  css_id is finally killed and
a minor update to device_cgroup; however, the pull request does lead
to a conflict in mm/memcontrol.c between the following two commits.

  b862783594847 ("memcg: stop using css id")
  bb4cc1a8b5eaf ("revert "memcg: get rid of soft-limit tree infrastructure"")

The former removes free_css_id() call from __mem_cgroup_free() and the
latter restores mem_cgroup_remove_from_trees() right above it leading
to context conflict.  The conflict looks like

  static void __mem_cgroup_free(struct mem_cgroup *memcg)
  {
	  int node;
	  size_t size = memcg_size();

  <<<<<<< HEAD
	  mem_cgroup_remove_from_trees(memcg);
	  free_css_id(&mem_cgroup_subsys, &memcg->css);

  =======
  >>>>>>> 73ba353471e0b692f398f3d63018b7f46ccf1d3e
	  for_each_node(node)
		  free_mem_cgroup_per_zone_info(memcg, node);

	  free_percpu(memcg->stat);

and can be resolved like the following.

  static void __mem_cgroup_free(struct mem_cgroup *memcg)
  {
	  int node;
	  size_t size = memcg_size();

	  mem_cgroup_remove_from_trees(memcg);

	  for_each_node(node)
		  free_mem_cgroup_per_zone_info(memcg, node);

	  free_percpu(memcg->stat);
