implementing synchronization

1. Explain why implementing synchronization primitives by disabling interrupts is not appropriate in a single-processor system if the synchronization primitives are to be used in user-level programs.

2. Explain why interrupts are not appropriate for implementing synchronization primitives in multiprocessor systems.

3. The Linux kernel has a policy that a process cannot hold a spinlock while attempting to acquire a semaphore. Explain why this policy is in place.

4. Describe two kernel data structures in which race conditions are possible. Be sure to include a description of how a race condition can occur.

5. Describe how the compare and swap() instruction can be used to provide mutual exclusion that satisfies the bounded-waiting requirement.
