The filesystem using libpuffs tells the kernel what operations should be
sent to userland when it calls puffs_init(). It can be done 
- by setting the list of wanted operation, in which case the kernel
never sends an unknown message, 
- by requesting all operations to be sent to userland. In that case an
unknown operation is handled in src/lib/libpuffs/dispatcher.c:dispatch()
                default:
                        printf("inval op %d\n", preq->preq_optype);
                        error = EINVAL;
                        break;
