FWIW, given that I am quoting "code rules!" to the gods of Linux on another lkml thread, I can hardly disagree here. If Nitin continues to develop his allocator and it proves better than xcfmalloc (and especially if it can replace zbud as well), we can consider replacing xcfmalloc later. Until zcache is promoted from staging, I think we have that flexibility. (Shameless advertisement though: The xcfmalloc allocator only applies to pages passed via frontswap, and on that other lkml thread lurk many people intent on shooting frontswap down. So, frankly, I'd prefer time to be spent on benchmarking zcache rather than on arguing about allocators which, as things currently feel to me on that other lkml thread, is not unlike rearranging deck chairs on the Titanic.
