Jens Axboe 8c0b563e9b io_uring/rw: ensure io->bytes_done is always initialized ... commit 0a535eddbe0dc1de4386046ab849f08aeb2f8faf upstream. If IOSQE_ASYNC is set and we fail importing an iovec for a readv or writev request, then we leave ->bytes_done uninitialized and hence the eventual failure CQE posted can potentially have a random res value rather than the expected -EINVAL. Setup ->bytes_done before potentially failing, so we have a consistent value if we fail the request early.
