From: Chuck Lever Subject: [PATCH 18/25] NFS: Remove the NIPQUAD from nfs_try_mount Date: Tue, 13 Nov 2007 13:32:35 -0500 Message-ID: <20071113183235.5087.90897.stgit@manray.1015granger.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Cc: netdev@vger.kernel.org To: nfs@lists.sourceforge.net Return-path: Received: from sc8-sf-mx1-b.sourceforge.net ([10.3.1.91] helo=mail.sourceforge.net) by sc8-sf-list2-new.sourceforge.net with esmtp (Exim 4.43) id 1Is0Yu-0000WN-Bh for nfs@lists.sourceforge.net; Tue, 13 Nov 2007 10:32:37 -0800 Received: from flpi101.sbcis.sbc.com ([207.115.20.70] helo=flpi101.prodigy.net) by mail.sourceforge.net with esmtp (Exim 4.44) id 1Is0Z0-0000Dn-1k for nfs@lists.sourceforge.net; Tue, 13 Nov 2007 10:32:42 -0800 List-Id: "Discussion of NFS under Linux development, interoperability, and testing." List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: nfs-bounces@lists.sourceforge.net Errors-To: nfs-bounces@lists.sourceforge.net 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.
