Also see Xen tmem (in drivers/xen). I am also working on a related project
called RAMster that uses frontswap. And someone has started code for KVM
to work with transcendent memory (including frontswap). But for now zcache
is the only non-virtualization in-kernel user for frontswap.

P.S. A recent build fix for zcache is necessary for it to work without
manual modification to the zcache Makefile.
See 8c70aac04e01a08b7eca204312946206d1c1baac in Linus's tree.
