Before I queue this, the series is missing two more follow-up fixes that both carry "Fixes: cccb45d7c429" and that are needed for the dl_server logic to behave correctly: 4717432dfd99 ("sched/deadline: Fix dl_server_stopped()") bb4700adc3ab ("sched/deadline: Always stop dl-server before changing parameters") Without 4717432dfd99 the dl_server_stopped() check is inverted (it returns the wrong polarity after cccb45d7c429), and without bb4700adc3ab the per-rq running_bw accounting can get out of sync when dl-server parameters change while it is still active. Could you send a v2 that includes both follow-ups on top of the existing three? Then this should be safe to apply as a whole. -- Thanks, Sasha
