My understanding is that zswap is lower level: only in the moment when a page _would_ be stored, the zswap code is called. That's why activating zsawp has absolutely no effect if there is no swap device: it simply is never called in this case. Concerning your other questions: The interface has changed several times. I guess the documentation is simply not up-to-date anymore...
