Hi Andrew, The whole patchset has been acked and reviewed by Michal and Tejun. Could you merge it into mm tree? =========== This patchset converts memcg to use cgroup->id, and then we remove cgroup css_id. As we've removed memcg's own refcnt, converting memcg to use cgroup->id is very straight-forward. v6: - rebased against mmotm 2013-09-20-15-59 - moved cgroup id check from mem_cgroup_css_alloc() to mem_cgroup_css_online() 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 | 248 +------------------------------------------------ mm/memcontrol.c | 66 +++++++------ 3 files changed, 41 insertions(+), 310 deletions(-) -- 1.8.0.2 -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
