Only one change is necessary: for the swap code to use readpage() instead of bmap(). I've been meaning to ask Stephen Tweedie about this at some stage. Presumably there's a good reason for using a bmap() interface given that readpage() is already available. (I've been told that WinNT uses readpage(), for example. I'm not sure how reliable that source is, though.)
If the aim is just to save disk space, then doing this is the way that requires least development effort.
pjm.
