Subject: svc: failed to register lockdv1 RPC service (errno 97).
Date: Sunday, May 10, 2009 - 8:48 pm

After switching from 2.6.29.2 to 2.6.30-rc5 I get this new message during 
boot of my home server:
   svc: failed to register lockdv1 RPC service (errno 97).

This looks to be the result of the following commit:
commit 363f724cdd3d2ae554e261be995abdeb15f7bdd9
Author: Chuck Lever <chuck.lever@oracle.com>
    SUNRPC: rpcb_register() should handle errors silently
    Move error reporting for RPC registration to rpcb_register's caller.

Question is: do I really want to know this? I assume the "failure" 
happened with previous kernels too, but silently.

If I do need to know this, it would be nice if the error was more 
informative. I had to grep the kernel source to see that 97 is
-EAFNOSUPPORT and that that means "Address family not supported by 
protocol". And even with that I don't know whether it's IPv4 or IPv6 
where the failure is.

My impression is that this is a bogus message from a user's perspective 
and that it should not be displayed.

Cheers,
FJP
