  "message": "perf: Optimize perf_event_task_sched_out\n\nRemove an update_context_time() call from the\nperf_event_task_sched_out() path and into the branch its needed.\n\nThe call was both superfluous, because __perf_event_sched_out()\nalready does it, and wrong, because it was done without holding\nctx-\u003elock.\n\nPlace it in perf_event_sync_stat(), which is the only place it\nis needed and which does already hold ctx-\u003elock.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nLKML-Reference: \u003c20091120212508.779516394@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
