+Subject: [PATCH 101/347] sched/fair: Make the hrtimers non-hard again
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.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.
