Ah, sorry, processing too much email backlog and left out some context... Kztmem is entirely in-kernel, no virtualization required (neither Xen nor KVM). I'll cc you when I post V1 soon but, yes, it is compressed *in-kernel* tmem, a more flexible/dynamic replacement for zcache and possibly also for zram as well, architected and designed to more easily (than zcache/zram) exploit some other directions I plan to take with tmem concepts, including (but not limited to) page-addressable memory (http://marc.info/?l=linux-mm&m=127811271605009). Kztmem is coded (at least for now) as a staging driver, but uses exactly the proposed cleancache (and frontswap) patches. Hope that helps!
