Oleg said that debug_locks_off() could've been called and thus prevented lockdep complaints about simple_lmk from appearing. To eliminate any possibility of that, I disabled debug_locks_off(). Oleg also said that __lock_acquire() could return early if lock debugging were somehow turned off after lockdep reported one bug. To mitigate any possibility of that as well, I threw in the BUG_ON() for good measure. I think at this point it's pretty clear that lockdep truly isn't complaining about simple_lmk's locking pattern, and that lockdep's lack of complaints isn't due to it being mysteriously turned off...
