I'm not convinced it's the _fastest way_. You're effectively
invalidating all the work done under drivers/staging so you might end up
in review limbo with your shiny new code...

AFAICT, your best bet is to first clean up zcache under driver/staging
and get that promoted under mm/zcache.c. You can then move on to the
more controversial ramster and figure out where to put the clustering
code, etc.
