 * Example using the "fksmb$pid" dtrace provider.
 * Traces all SMB commands using the probes:
 *	start, done
 * all of which have two args:
 *	args[0]: char * (probe-name)
 *	args[1]: ulong (struct smb_request *)
 *
 * Note: the "userland" type classifier causes dtrace to
 * automatically copyin the struct for us.  (Nice!)
