[PATCH V2 17/36] hrtimer: don't check if timer is queued in __remove_hrtimer()

From: Viresh Kumar
Date: Fri Apr 04 2014 - 02:47:55 EST


__remove_hrtimer() is called from three locations: remove_hrtimer(),
__run_hrtimer() and migrate_hrtimer_list(). And all these guarantee that timer
was queued earlier. And so there is no need to check if the timer is queued or
not in __remove_hrtimer().
