From 9d548b9c955c0709d1229d21d0bc14afa6b356de Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 15 Sep 2008 16:27:30 -0500 Subject: [PATCH] SUNRPC: Use short-hand IPv6 ANYADDR for RPCB_SET Clean up: When doing an RPCB_SET, make the kernel's rpcb client use the shorthand "::" for the universal form of the IPv6 ANY address. Without this patch, rpcbind will advertise: 0000:0000:0000:0000:0000:0000:0000:0000.x.y This is cosmetic only. It cleans up the display of information from /sbin/rpcinfo.
