The Wikipedia article I referenced describes zram as a swap device and
zswap as a cache front-ending the swap device, i.o.w. zswap can deal with
memory over-subscription by evicting pages to an external swap device:
zram can't do this because it IS the swap device.

The Wikipedia article describes them as alternatives.
