  "message": "sched: Remove unlikely() from ttwu_post_activation\n\nThe unlikely() used in ttwu_post_activation() tests if the rq-\u003eidle_stamp\nis set. But since this is for a wakeup, and wakeups happen when tasks\nblock on IO, and blocking tasks on IO may put the system into idle,\nthis can actually be a common occurence.\n\nRunning the annotated branch profiler on an average desktop running\nfirefox, evolution, xchat and distcc, the report shows:\n\n correct incorrect  %        Function             File              Line\n ------- ---------  -        --------             ----              ----\n34884862 146110926  80 ttwu_post_activation      sched.c            2309\n\n80% of the time, this unlikely is incorrect. Best not to assume what the\nresult is, and just remove the branch annotation.\n\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
