In Prоject 2, we used Linux kernel semаphоres tо solve the bounded-buffer producer-consumer problem. A producer threаd seаrches the task list for processes belonging to a given user, while a consumer thread calculates the elapsed time of each process found by the producer. (a) [10pts] When a semaphore is unavailable, the waiting task blocks. Linux also provides spinlocks, which use busy waiting. Compare semaphores and spinlocks, and explain the advantages of each synchronization mechanism. Organize your answer into separate bulleted lists for semaphores and spinlocks. Each bullet must clearly identify and explain one advantage. (b) [10pts] Which synchronization mechanism, semaphores or spinlocks, is more appropriate for coordinating the producer and consumer threads in this project? Explain your answer. Clearly label your answer to each subquestion. Unlabeled answers may not receive credit.
