  "message": "cgroup: implement cgroup_is_descendant()\n\nA couple controllers want to determine whether two cgroups are in\nancestor/descendant relationship.  As it\u0027s more likely that the\ndescendant is the primary subject of interest and there are other\noperations focusing on the descendants, let\u0027s ask is_descendent rather\nthan is_ancestor.\n\nImplementation is trivial as the previous patch guarantees that all\nancestors of a cgroup stay accessible as long as the cgroup is\naccessible.\n\ntj: Removed depth optimization, renamed from cgroup_is_ancestor(),\n    rewrote descriptions.\n\nSigned-off-by: Li Zefan \u003clizefan@huawei.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
