If anyone has any objections, please let me know. ------------------ From: Trond Myklebust [ Upstream commit 4b09ca1508a60be30b2e3940264e93d7aeb5c97e ] If connect() is returning ECONNRESET, it usually means that nothing is listening on that port. If so, a rebind might be required in order to obtain the new port on which the RPC service is listening. Fixes: fd01b2597941 ("SUNRPC: ECONNREFUSED should cause a rebind.")
