bug#25476: Test fail

[Ludovic Courtès]

Hi Maria,

Thanks for your report.  In practice you can safely ignore this test
failure.  We had a similar report earlier that this fails on Ubuntu:
<https://bugs.gnu.org/25476>.

Something we should do, though, is to at least skip the test when we
know we’re using a faulty kernel.  Currently we already have:

  ;; XXX: Skip this test when running Linux > 4.7.5 to work around
  ;; <https://bugzilla.kernel.org/show_bug.cgi?id=183461>.
  (when (or (not perform-container-tests?)
            (version>? (utsname:release (uname)) "4.7.5"))
    (test-skip 1))

Gábor, given what you wrote about Ubuntu’s 4.4 kernel, should we
explicitly flag “4.4.0-116-generic” in a similar way?  Would it be
enough?

Thank you both!

Ludo’.
