Uh, I realize I'm talking about the NFS server (callback rpc client) here and you were talking about the NFS client (callback rpc server)? In any case, no, I don't think there's any reason to support a UDP backchannel on client or server side. It would be interesting to test the current code and see what it actually does in this case. --b. > > So, agreed, making sure we error out in the UDP case (if we don't > already) would be a good idea. > > --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
