I would again like to mention that apart from highmem, xvmalloc is O(1) and is very memory efficient too. Sometime in future I hope to present it as replacement for funny SLOB allocator. For this I will require lot of data which is another major work....
For now, I will rename xvmalloc to rzmalloc and move it to drivers/block/ramzswap. As for data to justify ramzswap inclusion -- its going to be hard. It just 'feels' lot more responsive with compression but not sure how to quantify this. Maybe I will get some data by next release.
Thanks to you all for your reviews and suggestions.
