Subject: [patch 0/5] mm: memcontrol: eliminate charge reparenting v2
Date: Tue, 14 Oct 2014 12:20:32 -0400 [thread overview]
Message-ID: <1413303637-23862-1-git-send-email-hannes@cmpxchg.org> (raw)
Hi,
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]
