I know that’s not the source of the XFS issue, but it’s something that should be noted on the extension’s info page since DSL 4+ uses 2.4.31.This extension is not needed by later 3.x and not at all by 4.x as it has been incorporated into the base iso. It would only be necessary for very old versions of DSL. See Notes section on website.
Sometimes, additions to DSL come via a community built extension. The extension remains for those with versions of DSL prior to the extension's adoption into the iso.
