Subject: [PATCH] sched/fair: Make the hrtimers non-hard again
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.9-rt3.tar.xz
Since commit "sched/fair: Robustify CFS-bandwidth timer locking" both
hrtimer can run in softirq context because now interrupts are disabled
as part of the locking procedure.
