Comment 25 for bug 1842437

The reported failures for autopkgtest are unrelated
to this change on the probe of the nilfs filesystem.

Two are apparently failures in handling test reboot,
and another is lack of a kernel module.

I'll ask for retries on these, and do a quick check
on this module error.
