commit 504e518953a330c8d44a95bdd65a5c9f50f1012e
Author: Neil Brown <neilb@xxxxxxx>
Date: Thu Oct 16 14:15:16 2008 +1100
Make nfs_file_cred more robust.
As not all files have an associated open_context (e.g. device special
files), it is safest to test for the existence of the open context
before de-referencing it.

NFS: Enable NFSv4 callback server to listen on AF_INET6 sockets
Allow the NFS callback server to listen for requests via an AF_INET6 or
AF_INET socket when IPv6 support is present in the kernel.
