-Subject: sched/deadline: Always stop dl-server before changing parameters
-
-From: Juri Lelli <juri.lelli@redhat.com>
-
-commit bb4700adc3abec34c0a38b64f66258e4e233fc16 upstream.
-
-Commit cccb45d7c4295 ("sched/deadline: Less agressive dl_server
-handling") reduced dl-server overhead by delaying disabling servers only
-after there are no fair task around for a whole period, which means that
-deadline entities are not dequeued right away on a server stop event.
-However, the delay opens up a window in which a request for changing
-server parameters can break per-runqueue running_bw tracking, as
-reported by Yuri.
-
-Close the problematic window by unconditionally calling dl_server_stop()
-before applying the new parameters (ensuring deadline entities go
-through an actual dequeue).
