2.4.18 rpciod oops [xdr_encode_netobj]

[Jim Eshleman]

   FYI.  There was no apparent effect on the running system, an 8-way
8.5G (64G HIGHMEM) P3 Xeon, running 2.4.18 + XFS, NIS, NFS, sendmail,
etc.  Let me know if more info is needed.

Is it repeatable on a non-XFS patched kernel?

Cheers,

   Unfortunately I'm not able to try a non-XFS kernel on this machine.
