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I believe zcache is completely superceded by kztmem.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:
