From 5d8515caeb99940f5ed56d22a03aba20bbe7fdcb Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 10 Dec 2007 14:57:16 -0500 Subject: [PATCH] NFS: eliminate NIPQUAD(clp->cl_addr.sin_addr) To ensure the NFS client displays IPv6 addresses properly, replace address family-specific NIPQUAD() invocations with a call to the RPC client to get a formatted string representing the remote peer's address.
