From 7559c7a28fbcaa0bca028eeebd5f251b09befe6b Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 5 Dec 2006 16:35:37 -0500 Subject: [PATCH] SUNRPC: Make address format buffers more generic For now we will assume that all transports will use the address format buffers in the rpc_xprt struct to store their addresses. Change rpc_peer2str() to be a generic routine to handle this, and get rid of the print_address() op in the rpc_xprt_ops vector.
