As we've removed memcg's own refcnt, converting memcg to use cgroup->id is very straight-forward. The patchset is based on Tejun's cgroup tree. v5: - rebased against mmotm 2013-08-07-16-55 v4: - make cgroup_from_id() inline and check if cgroup_mutex is held. - add a comment for idr_remove() in cgroup_offline)fn(). v2->v3: - some minor cleanups suggested by Michal. - fixed the call to idr_alloc() in cgroup_init() in the first patch. Li Zefan (5): memcg: convert to use cgroup_is_descendant() memcg: convert to use cgroup id memcg: fail to create cgroup if the cgroup id is too big memcg: stop using css id cgroup: kill css_id -- include/linux/cgroup.h | 37 ---------- kernel/cgroup.c | 252 +--------------------------------------------------------------- mm/memcontrol.c | 69 +++++++++++------- 3 files changed, 43 insertions(+), 315 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
