I am heading to the airport shortly so this email is a bit hastily typed.

Perhaps a compromise can be reached where this code is merged as a driver
not a core mm component. There is a high bar to be in the MM - it has to
work with many many different configurations. 

And drivers don't have such a high bar. They just need to work on a specific
issue and that is it. If zswap ended up in say, drivers/mm that would make
it more palpable I think.

Thoughts?
