From: Suresh Jayaraman Subject: [PATCH] supress socket error when address family is not supported Patch-mainline: No References: bnc#670449 It was observed that when ipv6 module was not loaded and cannot be auto-loaded, when starting NFS server, the following error occurs: "rpc.nfsd: unable to create inet6 TCP socket: errno 97 (Address family not supported by protocol)" This is obviously a true message, but does not represent an "error" when ipv6 is not enabled. Rather, it is an expected condition. As such, it can be confusing / misleading / distracting to display it in this scenario. This patch instead of throwing error when a socket call fails with EAFNOSUPPORT, makes it as a NOTICE.
