Not sure on the SLUB/SLAB/SLOB/SLQB argument, but ramzez is basically just a port of compcache. I've tried to incorporate it into the BFS kernel, but Nokia screwed around so much with the swapping code (to try to align pages) that unfortunately it's unstable, especially with the swap notify patch (even when I modified it to try to allow for their swap_remap nonsense). This can be shown up very easily by simply running two memhog's of around 200MiB at the same time - OOM is the usual result, with the occasional complete system crash. Lovely..
