Yes, that is also what I meant. We now have a swapoff() system call that does all the work itself. My idea was to split that up: /* turn of swap device */ static int swapoff_one(struct swdevt *sp) { /* Do all things that we don't want to know about outside this function */ } /* turn off all swap devices */ int swapoff_all() { int index; struct swdevt *sp; for (sp = swdevt, index = 0; index < nswdev; index++, sp++) swapoff_one(sp); } So the swapoff() system call would call swapoff_one() and my code in kern/kern_swsuspend.c would call swapoff_all().
