  "message": "cgroup: remove cgroupfs_root-\u003erefcnt\n\nCurrently, cgroupfs_root and its -\u003etop_cgroup are separated reference\ncounted and the latter\u0027s is ignored.  There\u0027s no reason to do this\nseparately.  This patch removes cgroupfs_root-\u003erefcnt and destroys\ncgroupfs_root when the top_cgroup is released.\n\n* cgroup_put() updated to ignore cgroup_is_dead() test for top\n  cgroups.  cgroup_free_fn() updated to handle root destruction when\n  releasing a top cgroup.\n\n* As root destruction is now bounced through cgroup destruction, it is\n  asynchronous.  Update cgroup_mount() so that it waits for pending\n  release which is currently implemented using msleep().  Converting\n  this to proper wait_queue isn\u0027t hard but likely unnecessary.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
