3. Two processes ( 7 and 8 ) are currently on RL. Process 8 is at the head of the list and is running. The next field of process 8 points to process 7 , which is ready. Process 7 is currently holding two resources (15 and 25). The other_resources field of process 7 points to resource 15 , which in turn points to the next resource, 25 . a. Show all changes to the data structures after process 8 requests resource 15 . (Please fill updated values in the corresponding box below) b. Show all changes to the data structures after process 7 releases resource 15 Assume that processes are entered into RL at the end of the list. (Please fill updated values in the corresponding box below)
