[CCing Dave, Ben] Just a short summary as you were not on the CC list. This is sort of follow up on https://lkml.org/lkml/2012/9/3/211. The end result is slightly different because Tejun did a more generic cgroup solution (see bellow). I cannot do the same for OpenSUSE so I will stick with the memcg specific patch.

Just for the record, I will post backports of the patch I ended up using for openSUSE 11.4 and 12.[12] and SLES-SP2 as a reply to this email (and 2.6.32 in case somebody is interested). I hope other distributions can either go with this (which will never be merged but it should help to identify dubious usage of flat hierarchies without a risk of breaking anythign) or what Tejun has in his tree[1] 8c7f6edb (cgroup: mark subsystems with broken hierarchy support and whine if cgroups are nested for them) which is more generic but it is also slightly more intrusive. --- [1] - git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.7-hierarchy -- Michal Hocko SUSE Labs _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
