+Subject: [PATCH 097/347] time/hrtimer: avoid schedule_work() with interrupts
+ disabled
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+The NOHZ code tries to schedule a workqueue with interrupts disabled.
+Since this does not work -RT I am switching it to swork instead.
