SubjectRe: [RFC] cgroup TODOs
[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.
