I think current commit you are testing.

After the patch, it looks like following:

static coroutine_fn int sd_co_writev(BlockDriverState *bs, int64_t sector_num,
                        int nb_sectors, QEMUIOVector *qiov)
{
    SheepdogAIOCB *acb;
    int ret;
    int64_t offset = (sector_num + nb_sectors) * BDRV_SECTOR_SIZE;
    BDRVSheepdogState *s = bs->opaque;

    if (bs->growable && offset > s->inode.vdi_size) {
        ret = sd_truncate(bs, offset);
        if (ret < 0) {
            return ret;
        }
    }


Thanks
