The patch should apply to any 2.2 or 2.3 kernel, but for 2.3 it'll have the interesting side effect of nullifying the (minimal) page aging that's going on there. Expect a patch for the newest 2.3 tomorrow :) (if I'm not in a moving frenzy and packing my things like I should be doing by now) cheers, Rik -- The Internet is not a network of computers.
