If you don't recompile, kdump will print UNKNOWN(15) and a hexdump
of the corresponding ktr struct.

   607      1 mutt     UNKNOWN(15)
        000   00 00 00 00 01 00 00 00                          ........

If you add a new dtype to the kernel later and don't recompile
kdump, it will print a numeric value. For consistency, I'd like to
wrap it into "UNKNOWN":

   607      1 mutt     FD   file 2
   607      1 mutt     FD   UNKNOWN(9) 3
