From f3f4f4ed26b116f621596f74d42d2b736171e968 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Sun, 9 Aug 2009 15:09:29 -0400 Subject: [PATCH] NFS: Fix up new minorversion= option The new minorversion= mount option (commit 3fd5be9e) was merged at the same time as the recent sloppy parser fixes (commit a5a16bae), so minorversion= still uses the old value parsing logic. If the minorversion= option specifies a bogus value, it should fail with "bad value" not "bad option."
