Cgroup hierarchical support

Hello Tejun,

I'd like to ask which cgroup controllers actually support "hierarchical behavior". E.g. the children cgroups to be always bound by the limits of the ancestor group? So far the only one which seems to have this behavior is the memory cgroup with use_hierarchy set to 1. Also, I'm interested in such a behavior on the legacy hierarchy version of the code - e.g. not "sane_behavior" enabled mounts.

I think such a list might be added to the documentation?

Regards,
Nikolay

Hello, Nikolay.

All of them at this point, I think.

Thanks.
