(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 -- include/linux/cgroup.h | 44 ++------- kernel/cgroup.c | 302 +++++++++----------------------------------------------------- mm/memcontrol.c | 53 ++++++----- 3 files changed, 77 insertions(+), 322 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
