Respected sirIt's Himanshu Shukla B.Tech CSE Third Year. Actually in Stage 25 it is mentioned that implementation of Kill All function is final but there will be a problem in Stage 27 when we run a user program due to which swapper daemon was invoked after execution of user program is completed when we invoke Logout System call from shell swapper demon will be in TERMINATED state, which is not taken care of in Stage 27.
