Improving interoperability is a good thing.
Unfortunately, this patch alone isn't a good answer.
1) All non-root NFS mount attempts would now fail.
2) The maximum number of NFS mounts would now be limited
by the limited number of "reserved ports".
Also, I would like to point out that the requirement that
NFS connections come from reserved ports doesn't actually
improve security... it just limits interoperability.
Thanks
