Vladimir, might we need get_online_mems/put_online_mems here,
or if node gets offline this wont be a problem? (Asking
because i don't know).

I only need to dereference page structs corresponding to the node here,
and page structs are not freed when the node gets offline AFAICS, so I
guess it must be safe.

OK, thanks for info!
