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

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]
