Since "block: support large requests in blk_rq_map_user_iov" we started to call it with partially drained iter; that works fine on the write side, but reads create a copy of iter for completion time. And that needs to take the possibility of ->iov_iter != 0 into account... Cc: stable@vger.kernel.org #v4.5+ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
