+Subject: sched/deadline: Zero out positive runtime after throttling constrained tasks
+
+From: Xunlei Pang <xlpang@redhat.com>
+
+commit ae83b56a56f8d9643dedbee86b457fa1c5d42f59 upstream.
+
+When a contrained task is throttled by dl_check_constrained_dl(),
+it may carry the remaining positive runtime, as a result when
+dl_task_timer() fires and calls replenish_dl_entity(), it will
+not be replenished correctly due to the positive dl_se->runtime.
+
+This patch assigns its runtime to 0 if positive after throttling.

+commit eb94588dabec82e012281608949a860f64752914 upstream.
+
+In a previous patch a hpsa_scsi_dev_t.volume_offline update line has
+been removed, so let us put it back..
