BTW I think we should hold off on converting zswap for now.

The reason is that I'd like to try out the new interface on IPcomp
and make sure that it actually is able to do decompression piecemeal
which is the main advantage over the existing interface for IPcomp
where we allocate for the worst-case (64K vs average packet size
of 1.5K).

In that process we may have to tweak the interface.

Thanks,
