yes, you are right. if I only handle the -ESRCH , like:

-       return __fib_lookup(net, flp, res);
+
+       err = __fib_lookup(net, flp, res);
+       if(err == -ESRCH)
+               return -ENETUNREACH;
+
+       return err;

I think it will be ok, after all, it looks confused that err is *No
such process* when add a route.

thanks for your reply.
