The lkdtm_STACKLEAK_ERASING() test is instrumentable and runs with IRQs unmasked, so it's possible for unrelated code to clobber the task stack and/or manipulate current->lowest_stack while the test is running, resulting in spurious failures. The regular stackleak erasing code is non-instrumentable and runs with IRQs masked, preventing similar issues. Make the body of the test non-instrumentable, and run it with IRQs masked, avoiding such spurious failures.
