Consider the code example for allocating and releasing processes shown in Figure 5.23. 5.20 Exercises 247 Identify the race condition(s) Assume you have a mutex lock named mutex with the operations acquire) and release ). Indicate where the locking needs to be placed to prevent the race condition(s). Could we replace the integer variable a. b. c. int number-of-processes 0 = with the atomic integer atomic-t number-of-processes 0 = to prevent the race condition(s)
