Subject: [PATCH v3 0/2] iov_iter: allow iov_iter_get_pages_alloc to allocate more pages per call

Small respin of the patch that I sent yesterday for the same thing.

This moves the maxsize handling into iov_iter_pvec_size, so that we don't
end up iterating past the max size we'll use anyway when trying to
determine the pagevec length.

Also, a respun patch to make ceph use iov_iter_get_pages_alloc instead of
trying to do it via its own routine.

Al, if these look ok, do you want to pick these up or shall I ask
Ilya to merge them via the ceph tree?

    call
  ceph: switch DIO code to use iov_iter_get_pages_alloc
