Vladimir Davydov 7feee590bb memcg: disable hierarchy support if bound to the legacy cgroup hierarchy ...

If the memory cgroup controller is initially mounted in the scope of the
default cgroup hierarchy and then remounted to a legacy hierarchy, it will
still have hierarchy support enabled, which is incorrect.  We should
disable hierarchy support if bound to the legacy cgroup hierarchy.
