+Subject: [PATCH 111/347] sched: Use the proper LOCK_OFFSET for cond_resched()
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+RT does not increment preempt count when a 'sleeping' spinlock is
+locked. Update PREEMPT_LOCK_OFFSET for that case.
