To elaborate on that: 1) there already is lots of policy in the kernel (scheduler, page stealing code, users can nice-down-but-not-up, ...) 2) thrashing and OOM are relatively rare situations 3) I can see absolutely no reason why you would ever want to take a 2 kB piece of code from the kernel and put it in a 32 kB userland daemon (which would need another 32 kB of kernel overhead for task struct, pagetables, etc..) regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to lose... http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com.br/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
