Waiman Long 5149cbac42 locking/rwsem: Add DEBUG_RWSEMS to look for lock/unlock mismatches ... For a rwsem, locking can either be exclusive or shared. The corresponding exclusive or shared unlock must be used. Otherwise, the protected data structures may get corrupted or the lock may be in an inconsistent state. In order to detect such anomaly, a new configuration option DEBUG_RWSEMS is added which can be enabled to look for such mismatches and print warnings that that happens.
