  "message": "sched: Simplify cpu-hot-unplug task migration\n\nWhile discussing the need for sched_idle_next(), Oleg remarked that\nsince try_to_wake_up() ensures sleeping tasks will end up running on a\nsane cpu, we can do away with migrate_live_tasks().\n\nIf we then extend the existing hack of migrating current from\nCPU_DYING to migrating the full rq worth of tasks from CPU_DYING, the\nneed for the sched_idle_next() abomination disappears as well, since\nidle will be the only possible thread left after the migration thread\nstops.\n\nThis greatly simplifies the hot-unplug task migration path, as can be\nseen from the resulting code reduction (and about half the new lines\nare comments).\n\nSuggested-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c1289851597.2109.547.camel@laptop\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
