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