For questions 37–39, consider the following two lock implementations running on a multiprocessor system. Lock A: typedef struct { int flag; } lock_A_t; void acquire_A(lock_A_t *lock) { while (lock->flag == 1) ; // spin lock->flag = 1; } void release_A(lock_A_t *lock) { lock->flag = 0; } Lock B: typedef struct { int ticket; int turn; } lock_B_t; void acquire_B(lock_B_t *lock) { int myturn = FetchAndAdd(&lock->ticket); while (lock->turn != myturn) ; // spin } void release_B(lock_B_t *lock) { lock->turn++; } Where FetchAndAdd atomically increments *addr and returns the old value: int FetchAndAdd(int *addr) { int old = *addr; *addr = old + 1; return old; }

Consider this thread_join implementation: void thread_join() { mutex_lock(&m); if (done == 0) cond_wait(&cv, &m); mutex_unlock(&m); } void thread_exit() { mutex_lock(&m); done = 1; cond_signal(&cv); mutex_unlock(&m); } True/False: This implementation is correct: thread_join will always wait until the child thread has called thread_exit.

Deadlock can occur even if only two of the four necessary conditions (mutual exclusion, hold and wait, no preemption, circular wait) are present.

Which of the following changes to thread3 would eliminate the possibility of deadlock?
