The patch titled Subject: memcg: disable hierarchy support if bound to the legacy cgroup hierarchy has been removed from the -mm tree. Its filename was memcg-disable-hierarchy-support-if-bound-to-the-legacy-cgroup-hierarchy.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx> Subject: 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.
