From 3832591e6fa53d8126d5e21446f225cda278d91a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 19 Jun 2015 13:04:13 -0400 Subject: SUNRPC: Handle connection issues correctly on the back channel If the back channel is disconnected, we can and should just fail the transmission. The expectation is that the NFSv4.1 server will always retransmit any outstanding callbacks once the connection is re-established.
