The same problem is for .skip_filesystems on tests which does not use<br>
.all_filesystems. We only haven't noticed, because there was no reason to skip<br>
ext[234] so far. I'm looking into this.<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">This seems a bit tricky to distinguish EXT2,3,4, from what I know,</div><div class="gmail_default" style="font-size:small">they use the same magic number.

BTW .skip_filesystems without .all_filesystems have other problems, e.g. using<br>
filesystems which aren't in fs_type_whitelist[] array (e.g. ramfs, nfs).<br>
That'd be nice to fix after the release.<br></blockquote><div><br></div><div class="gmail_default" style="font-size:small">+1</div><div class="gmail_default" style="font-size:small"><br></div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>Regards,<br></div><div>Li Wang<br></div></div></div></div>
