-Subject: [PATCH] sched/deadline: Ensure inactive_timer runs in hardirq
- context
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.17-rt9.tar.xz
-
-SCHED_DEADLINE inactive timer needs to run in hardirq context (as
-dl_task_timer already does) on PREEMPT_RT
-
-Change the mode to HRTIMER_MODE_REL_HARD.
-
-[ tglx: Fixed up the start site, so mode debugging works ]
