If progress stalls, notify_host() tries another IP address. This means sm-notify will generate a fresh rpcbind query. After an RPC succeeds, be sure to reset host->retries so sm-notify doesn't start walking down the host's addrinfo list when we _are_ making progress. In the common case, if the host responds, we avoid extra rpcbind queries and send all requests for the host to the same IP address. Signed-off-by: Chuck Lever Signed-off-by: Steve Dickson ---
