kunit: make test->lock irq safe
The upcoming SLUB kunit test will be calling kunit_find_named_resource()
from a context with disabled interrupts. That means kunit's test->lock
needs to be IRQ safe to avoid potential deadlocks and lockdep splats.
This patch therefore changes the test->lock usage to spin_lock_irqsave()
and spin_unlock_irqrestore().
