Yeah, I overlooked the importance of preserving prefetch_area (which
explains the unlikely you had). But my intent was to make your code
less "special"; your if (DM_PREFETCH_CHUNKS) do { } while() code to
avoid the extra indentation is pretty ugly.
Given your current code, DM_PREFETCH_CHUNKS is always 12 so why not just
remove the check?
