  25  * FS_Handler
  26  *
  27  * Description:
  28  *      Handler routine passed to the fsprobe module.  This handler is
  29  *      called immediately after a poll of all the FileServers has taken
  30  *      place.  All it needs to know is exported by the fsprobe module,
  31  *      namely the data structure where the probe results are stored.
  32  *
  33  * Arguments:
  34  *      None.
  35  *
  36  * Returns:
  37  *      0 on success,
  38  *      -1 otherwise.
  39  *
  40  * Environment:
  41  *      See above.  All we do now is print out what we got.
  42  *
  43  * Side Effects:
  44  *      As advertised.
