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().
