When I read the runnable load avg code, I found the task's avg.load_avg_contrib mainly updated in enqueue/dequeue, and the 'curr' task in sched_tick. So, if a sleep long time task is waked/added and kept on a cpu, but the task is never be the 'curr' in sched_tick. Then the task's load contrib will never be updated and keep small.
what I missed? or Is it really?
