  31  * Description:
  32  *      Handler routine passed to the fsprobe module.  This handler is
  33  *      called immediately after a poll of all the FileServers has taken
  34  *      place.  All it needs to know is exported by the fsprobe module,
  35  *      namely the data structure where the probe results are stored.
  36  *
  37  * Arguments:
  38  *      None.
  39  *
  40  * Returns:
  41  *      0 on success,
  42  *      -1 otherwise.
  43  *
  44  * Environment:
  45  *      See above.  All we do now is print out what we got.
  46  *
  47  * Side Effects:
  48  *      As advertised.
