md: Does the thread entering the wait queue violate the semantics of REQ_NOWAIT in raid5_make_request() ?

static bool raid5_make_request(struct mddev *mddev, struct bio * bi)
{
        ...

        if ((bi->bi_opf & REQ_NOWAIT) &&
            (conf->reshape_progress != MaxSector) &&
            get_reshape_loc(mddev, conf, logical_sector) ==
LOC_INSIDE_RESHAPE) {
                bio_wouldblock_error(bi);
                if (rw == WRITE)
                        md_write_end(mddev);
                return true;
        }

        if (likely(conf->reshape_progress == MaxSector)) {
                ...
        } else {
                add_wait_queue(&conf->wait_for_reshape, &wait);
                on_wq = true;
        }

        ...
}


In raid5_make_request(), if a reshape is progressing and the current
IO request is not within the reshape range and has the REQ_NOWAIT
flag, does the thread entering the wait queue violate the semantics of
REQ_NOWAIT?
