From e851db5b05408b89b9a9429a66814b79fabee2a1 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 30 Jun 2008 18:45:30 -0400 Subject: [PATCH] SUNRPC: Add address family field to svc_serv data structure Introduce and initialize an address family field in the svc_serv structure. This field will determine what family to use for the service's listener sockets and what families are advertised via the local rpcbind daemon. Signed-off-by: Chuck Lever Signed-off-by: J.
