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().
