+Subject: [PATCH 178/347] block: mq: use cpu_light()
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+there is a might sleep splat because get_cpu() disables preemption and
+later we grab a lock. As a workaround for this we use get_cpu_light().
