(This patchset depends on "memcg: make memcg's life cycle the same as cgroup")
This patchset converts memcg to always use cgroup->id, and then kills
css_id.
As we've removed memcg's own refcnt, converting memcg to use cgroup->id
is very straight-forward.
Li Zefan (8):
cgroup: implement cgroup_is_ancestor()
cgroup: implement cgroup_from_id()
memcg: convert to use cgroup_is_ancestor()
memcg: convert to use cgroup_from_id()
memcg: convert to use cgroup->id
memcg: fail to create cgroup if the cgroup id is too big
memcg: don't use css_id any more
cgroup: kill css_id
