Should be the same as:

            case 0:
              starts_group = true;
              /* fallthru */
            case 1:
            case 2:
              s390_sched_state++;
              break;
            case S390_SCHED_STATE_NORMAL:
              starts_group = true;
              s390_sched_state = 1;
              break;
            case S390_SCHED_STATE_CRACKED:
              s390_sched_state = S390_SCHED_STATE_NORMAL;
              break;
            }

Ok with that change. Thanks!
