From f0e1266ed24b8a69655e1ab7fb618dbf6730879b Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Mon, 13 Jul 2020 17:19:44 +0300 Subject: ovl: fix mount option checks for nfs_export with no upperdir Without upperdir mount option, there is no index dir and the dependency checks nfs_export => index for mount options parsing are incorrect. Allow the combination nfs_export=on,index=off with no upperdir and move the check for dependency redirect_dir=nofollow for non-upper mount case to mount options parsing.
