6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chuck Lever <chuck.lever@xxxxxxxxxx> commit 197115ebf358cb440c73e868b2a0a5ef728decc6 upstream. When an RPC Call message cannot be pulled from the client, that is a message loss, by definition. Close the connection to trigger the client to resend.
