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.
