  "message": "cgroups: fix cgroup_iter_next() bug\n\nWe access res-\u003ecgroups without the task_lock(), so res-\u003ecgroups may be\nchanged.  it\u0027s unreliable, and \"if (l \u003d\u003d \u0026res-\u003ecgroups-\u003etasks)\" may be\nfalse forever.\n\nWe don\u0027t need add any lock for fixing this bug.  we just access to struct\ncss_set by struct cg_cgroup_link, not by struct task_struct.\n\nSince we hold css_set_lock, struct cg_cgroup_link is reliable.\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nReviewed-by: Paul Menage \u003cmenage@google.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
