Peter Zijlstra 741ba80f6f sched: Relax the set_cpus_allowed_ptr() semantics ... Now that we have KTHREAD_IS_PER_CPU to denote the critical per-cpu tasks to retain during CPU offline, we can relax the warning in set_cpus_allowed_ptr(). Any spurious kthread that wants to get on at the last minute will get pushed off before it can run. While during CPU online there is no harm, and actual benefit, to allowing kthreads back on early, it simplifies hotplug code and fixes a number of outstanding races.
