From 338320345b40eb7c63592f40d25cbd58ccf99548 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 10 Dec 2007 14:59:13 -0500 Subject: [PATCH] NFS: Remove the NIPQUAD from nfs_try_mount In the name of address family compatibility, we can't have the NIP_FMT and NIPQUAD macros in nfs_try_mount(). Instead, we can make use of an unused mount option to display the mount server's hostname.
