[PATCH] sched/rt: Make update_curr_rt() more accurate

rq->clock_task may be updated between the two calls of rq_clock_task() in update_curr_rt(). Calling rq_clock_task() only once makes it more accurate and efficient, taking update_curr() as reference. Signed-off-by: Wen Yang Reviewed-by: Jiang Biao --- kernel/sched/rt.c | 5 +++-- 1 file changed
