The same problem is for .skip_filesystems on tests which does not use
.all_filesystems. We only haven't noticed, because there was no reason to skip
ext[234] so far. I'm looking into this.

BTW .skip_filesystems without .all_filesystems have other problems, e.g. using
filesystems which aren't in fs_type_whitelist[] array (e.g. ramfs, nfs).
That'd be nice to fix after the release.

Kind regards,
Petr
