SCHED_DEADLINE inactive timer needs to run in hardirq context (as dl_task_timer already does).
Make it HRTIMER_MODE_REL_HARD. Signed-off-by: Juri Lelli <[email protected]> --- Hi, Both v4.19-rt and v5.2-rt need this. Mainline "sched: Mark hrtimers to expire in hard interrupt context" series needs this as well ([email protected] in particular). Do I need to send out a separate patch for it?
