Description

In distribute_txn_commit_batchid_update:

        rc = dt_trans_start_local(env, tdtd->tdtd_lut->lut_bottom, th);
        if (rc < 0)
                GOTO(stop, rc);

        dt_trans_cb_add(th, &dtbd->dtbd_cb);
        if (rc < 0)
                GOTO(stop, rc);

Clearly there's an rc assignment missing?
