The issue of lazy > reclamation is pretty much independent of the allocator underneath; I We really should integrate this _now_, with the twist that pages which could form a larger buddy should be immediately deallocated. This can give us a cheap way to: - create larger memory buddies - remove some of the pressure on the buddy allocator (no need to grab that last 64 kB area when 25% of user pages are lazy reclaim) Rik. +-------------------------------------------------------------------+ | Linux memory management tour guide.
