IMHO, the fastest way to get the best zcache into the kernel and
to distros and users is to throw away the "demo" version, move forward
to a new solid well-designed zcache code base, and work together to
build on it.  There's still a lot to do so I hope we can work together.

I'm not convinced it's the _fastest way_.

<grin> I guess I meant "optimal", combining "fast" and "best".

You're effectively
invalidating all the work done under drivers/staging so you might end up
in review limbo with your shiny new code...

Fixing the fundamental design flaws will sooner or later invalidate
most (or all) of the previous testing/work anyway, won't it?  Since
any kernel built with staging is "tainted" already, I feel like now
is a better time to make a major design transition.

I suppose:

 (E) replace "demo" zcache with new code base and keep it
     in staging for another cycle

I go for (E). Please send your refactoring code as formal patch.
Thanks.
