  "message": "sched: Make select_fallback_rq() cpuset friendly\n\nIntroduce cpuset_cpus_allowed_fallback() helper to fix the cpuset problems\nwith select_fallback_rq(). It can be called from any context and can\u0027t use\nany cpuset locks including task_lock(). It is called when the task doesn\u0027t\nhave online cpus in -\u003ecpus_allowed but ttwu/etc must be able to find a\nsuitable cpu.\n\nI am not proud of this patch. Everything which needs such a fat comment\ncan\u0027t be good even if correct. But I\u0027d prefer to not change the locking\nrules in the code I hardly understand, and in any case I believe this\nsimple change make the code much more correct compared to deadlocks we\ncurrently have.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c20100315091027.GA9155@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
