+Subject: [PATCH 247/323] lockdep: selftest: Only do hardirq context test for
+ raw spinlock
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+On -rt there is no softirq context any more and rwlock is sleepable,
+disable softirq context test and rwlock+irq test.
