      void tgt_grant_discard(struct obd_export *exp)
...
        if (tgd->tgd_tot_granted < ted->ted_grant) {
                CERROR("%s: tot_granted %llu < cli %s/%p ted_grant %ld\n",
                       obd->obd_name, tgd->tgd_tot_granted,
                       exp->exp_client_uuid.uuid, exp, ted->ted_grant);
        }
        tgd->tgd_tot_granted -= ted->ted_grant;
...

      If tgd->tgd_tot_granted < ted->ted_grant the decrement makes tgd_tot_granted too big.
