e behavior of < 0 return on
error or > 0 return if we mapped some pages. Callers that can possibly ask
to map 0 pages can get 0 pages back - kind of expected - and I don't see
any benefit in trying to rewrite these callers to handle -EINVAL instead...

Looks good to me. You can add:

MM tree would be one candidate for routing but there are other options that
would make sense as well - Dan's tree, VFS tree, or even I can pickup the
patches to my tree if needed. But let's worry about the routing after we
have working and reviewed patches...
t; pretty bad... So Thanks Jan... ;-)
For your function, I'd choose a name like vaddr_pin_leased_pages() so that
association with a lease is clear from the name :) Also I'd choose the
counterpart to be vaddr_unpin_leased_page[s](). Especially having put_page in
the name looks confusing to me...
