From 7bbceb6f2bdda67054bc66035a9543623e539126 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 2 Mar 2012 14:00:20 -0500 Subject: [PATCH] NFS: Ensure we display the minor version correctly in /proc/mounts etc. The 'minorversion' mount option is now deprecated, so we need to display the minor version number in the 'vers=' format.
