Sebastian Andrzej Siewior 6c11c6e3d5 locking/mutex: Test for initialized mutex ... An uninitialized/ zeroed mutex will go unnoticed because there is no check for it. There is a magic check in the unlock's slowpath path which might go unnoticed if the unlock happens in the fastpath. Add a ->magic check early in the mutex_lock() and mutex_trylock() path.
