memcg: memory cgroup hierarchical reclaim
This patch introduces hierarchical reclaim. When an ancestor goes over
its limit, the charging routine points to the parent that is above its
limit. The reclaim process then starts from the last scanned child of the
ancestor and reclaims until the ancestor goes below its limit.
[akpm@linux-foundation.org: coding-style fixes]
[d-nishimura@mtf.biglobe.ne.jp: mem_cgroup_from_res_counter should handle both mem->res and mem->memsw]
