+Subject: [PATCH 230/323] block/mq: do not invoke preempt_disable()
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+preempt_disable() and get_cpu() don't play well together with the sleeping
+locks it tries to allocate later.
+It seems to be enough to replace it with get_cpu_light() and migrate_disable().
