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?
Jeff Layton (2):
iov_iter: allow iov_iter_get_pages_alloc to allocate more pages per
call
ceph: switch DIO code to use iov_iter_get_pages_alloc
