Christoph Hellwig 4d6af73d9e block: support large requests in blk_rq_map_user_iov
This patch adds support for larger requests in blk_rq_map_user_iov by
allowing it to build multiple bios for a request.  This functionality
used to exist for the non-vectored blk_rq_map_user in the past, and
this patch reuses the existing functionality for it on the unmap side,
which stuck around.  Thanks to the iov_iter API supporting multiple
bios is fairly trivial, as we can just iterate the iov until we've
consumed the whole iov_iter.
