+Subject: [PATCH 239/342] x86: lazy-preempt: properly check against
+ preempt-mask
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=62de1107905ffc4ce432b5192aa4e86cba2ea98b
+
+should_resched() should check against preempt_offset after unmasking the
+need-resched-bit. Otherwise should_resched() won't work for
+preempt_offset != 0 and lazy-preempt set.
