Subject: [PATCH 235/333] lockdep: selftest: Only do hardirq context test for
|
|
raw spinlock
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.148-rt64.tar.xz
|
|
|
|
On -rt there is no softirq context any more and rwlock is sleepable,
|
|
disable softirq context test and rwlock+irq test.
