September was a very hectic month for me. One consequence of this change is that lockd always listens on TCP even if NFSD and NFS are only using UDP. Do we care? I suspect not. An alternative fix to the problem would be to always listen on UDP and only listen on TCP if it was requested. This would probably be a smaller code change, and might in some sense be more flexible. Will we ever want to talk NLM over any other protocol? RDMA? Is UDP6 a different protocol in this context? I suspect not. I guess I have a small leaning towards just always listening on UDP and leaving everything else the same, but it is small, not strong. So unless either of you lean the same way I'm happy to give my Acked-By: NeilBrown <neilb@xxxxxxx> to the current patches.
