Exercise 2.5.1: Request and release functions in action. About 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.
