Thomas Gleixner 45f67f30a2 locking/rtmutex: Add a lockdep assert to catch potential nested blocking ... There used to be a BUG_ON(current->pi_blocked_on) in the lock acquisition functions, but that vanished in one of the rtmutex overhauls. Bring it back in form of a lockdep assert to catch code paths which take rtmutex based locks with current::pi_blocked_on != NULL.
