sched: Fix runnable condition for stoptask Heiko reported that the TASK_RUNNING check is not sufficient for CONFIG_PREEMPT=y since we can get preempted with !TASK_RUNNING. He suggested adding a ->se.on_rq test to the existing TASK_RUNNING one, however TASK_RUNNING will always have ->se.on_rq, so we might as well reduce that to a single test. [ stop tasks should never get preempted, but its good to handle this case correctly should this ever happen ] Reported-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
