I understand. I assumed cherry-picking the two relevant patches from the
series would not be a problem here. I was wrong.

Next time I will make sure to either do a separate failing test patch
and and cross reference in the cover letters, or to first do the fix and
then improve the test coverage so the bug does not come back.

Should I send a v2 with the two questionable patches (the failing test
and the revert of it) removed right away?
