Subject: lockdep: selftest: Only do hardirq context test for raw spinlock
From: Yong Zhang <yong.zhang0@gmail.com>
Date: Mon, 16 Apr 2012 15:01:56 +0800
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.21-rt34.tar.xz
From: Yong Zhang <yong.zhang@windriver.com>
On -rt there is no softirq context any more and rwlock is sleepable,
disable softirq context test and rwlock+irq test.
