From 6738b2512bdf93ffbefe108b38a9165d5a718c3f Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 24 Jun 2008 16:33:54 -0400 Subject: [PATCH] NFS4: Set security flavor default for NFSv4 mounts like other defaults Set the default security flavor when we set the other mount option default values for NFSv4. This cleans up the NFSv4 mount option parsing path to look like the NFSv2/v3 one.
