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.
