We don't need to call this for every loop. This is particularly troublesome if we are task_work intensive, and get woken more often than we desire due to that. Just do it at the end, that's always safe as we initialize the waitqueue list head anyway. This can save a considerable amount of hammering on the waitqueue lock, which is also hot from the request completion side. Signed-off-by: Jens Axboe <axboe@kernel.dk>
