[PATCH v4 4/4] mutex: w/w mutex slowpath debugging

From: Daniel Vetter Injects EDEADLK conditions at pseudo-random interval, with exponential backoff up to UINT_MAX (to ensure that every lock operation still completes in a reasonable time). This way we can test the wound slowpath even for ww mutex users where contention is never expected, and th
