[patch 0/5] mm: memcontrol: eliminate charge reparenting v2

From: Johannes Weiner
Date: Tue Oct 14 2014 - 12:22:12 EST


this series gets rid of charge reparenting at cgroup deletion, which
is possible now that the css can outlive the user-visible cgroup. Any
cache charges left after cgroup deletion simply remain with their css,
where they continue to get reclaimed during pressure on the parent.

Version 2:

- remove memcg->dead_count [vladimir]
- restore iterator generations [vladimir]
- restore memcg-initialized test [michal]
- document shared walk lockless magic [michal]
- split out sync stock draining removal [michal]
