  18  * Example using the "smb" dtrace provider.
  19  * Traces all SMB commands.
  20  *
  21  * All these probes provide:
  22  *      args[0]  conninfo_t
  23  *      args[1]  smbopinfo_t
  24  * Some also provide one of: (not used here)
  25  *      args[2]  smb_name_args_t
  26  *      args[2]  smb_open_args_t
  27  *      args[2]  smb_rw_args_t
  28  *
  29  * Usage: smb-trace.d [<client ip>|all [<share path>|all] [<zone id>]]]
  30  *
  31  * example: smb_trace.d 192.168.012.001 mypool_fs1  0
  32  *
  33  * It is valid to specify <client ip> or <share path> as "all" to
  34  * print data for all clients and/or all shares.
  35  * Omitting <zone id> will print data for all zones.
