this cleanup project is already well documented here: http://fsdev.net/wiki/index.php?title=Power_of_2_stuff and it's unlikely that you'd get a big patch in that tries to do all of that at once. it's much easier to do it a subsystem at a time. rday p.s. that wiki page could probably use some updating. -- ======================================================================== Robert P.
