de4f5fed3f231a8ff4790bf52975f847b95b85ea is the first bad commit commit de4f5fed3f231a8ff4790bf52975f847b95b85ea Author: Jens Axboe Date: Wed Mar 29 08:52:15 2023 -0600 iov_iter: add iter_iovec() helper This returns a pointer to the current iovec entry in the iterator. Only useful with ITER_IOVEC right now, but it prepares us to treat ITER_UBUF and ITER_IOVEC identically for the first segment. Rename struct iov_iter->iov to iov_iter->__iov to find any potentially troublesome spots, and also to prevent anyone from adding new code that accesses iter->iov directly.
