Johannes Weiner b2052564e6 mm: memcontrol: continue cache reclaim from offlined groups ... On cgroup deletion, outstanding page cache charges are moved to the parent group so that they're not lost and can be reclaimed during pressure on/inside said parent. But this reparenting is fairly tricky and its synchroneous nature has led to several lock-ups in the past. Since c2931b70a3 ("cgroup: iterate cgroup_subsys_states directly") css iterators now also include offlined css, so memcg iterators can be changed to include offlined children during reclaim of a group, and leftover cache can just stay put. There is a slight change of behavior in that charges of deleted groups no longer show up as local charges in the parent. But they are still included in the parent's hierarchical statistics.
