Test overlay mount operation which has supported feature set, and
test mount operation with feature mount options:
- Check overlay mount with enabled redirect_dir/index/nfs_export
mount options
- Check overlay mount with supported redirect_dir/index/nfs_export
feature on the upper root dir
- Check overlay mount with supported redirect_dir/index/nfs_export
feature on the lower root dir only
Mount operation should succeed if supported features is detected on
the underlying root dir. One feature should be set on the upper
root dir if user give the enabled mount option or the same feature
is detected on the lower root dir.
