    I wanted to give Nitin a week to respond, but I guess he
    continues to be offline.

    I believe zcache is completely superceded by kztmem.
    Kztmem, like zcache, is dependent on cleancache
    getting merged.

    Kztmem may supercede zram also although frontswap (which
    kztmem uses for a more dynamic in-memory swap compression)
    and zram have some functional differences that support
    both being merged.

    For latest kztmem patches and description, see:

    Thanks,
    Dan
