Linus Torvalds 6631e635c6 block: don't flush plugged IO on forced preemtion scheduling 
We really only want to unplug the pending IO when the process actually
goes to sleep.  So move the test for flushing the plug up to the place
where we actually deactivate the task - where we have properly checked
for preemption and for the process really sleeping.
