The patches in the paper don't get the kernel nearly that involved. They add a system call called vm_relinquish which means (roughly) "please swap out this page soon" and a way for the process to say "please send me a real-time signal when you're about to page out one of my pages". There is a version of their patch here (see also description). I also see a vm_getswaprate system call which lets the process ask how much it is paging. I think that's about it (the patch also includes Scott Kaplans lightweight version of Rik van Riels reverse
mapping patch but unless I'm mistaken that was long ago merged into Linux).
