ZTEST()

ZTEST	(	interrupt_feature	,
		test_prevent_interruption
	)

Test interrupt prevention.

This routine tests if the kernel is capable of preventing interruption, by locking interrupts and busy-waiting to see if the system timer interrupt is serviced while interrupts are locked; in addition, this test also verifies that the system timer interrupt is serviced after interrupts are unlocked.
