Hi Marek,

Thanks for keeping up this work! I really hope it works out for the
next merge window.

Can you clarify these? I believe the contiguous memory areas in highmem
is something that should really be after the existing code is merged
into the upstream kernel and should better not be listed as TODO here.

I haven't followed the last two releases so closely. It seems that
in v17 the movable pages with pending i/o was still a major problem
but in v18 you added a solution. Is that right? What is still left
to be done here then?
