Hmmm...

To me, that sounds like a really good compromise.  Then anyone
who wants to experiment with compressed swap pages can do so by
enabling the zswap driver.  And the harder problem of deeply integrating
compression into the MM subsystem can proceed in parallel
by leveraging and building on the best of zswap and zcache
and zram.

Seth, if you want to re-post zswap as a driver... even a
previous zswap version with zsmalloc and without writeback...
I would be willing to ack it.  If I correctly understand
Mel's concerns, I suspect he might feel the same.
