I think you are right here.  However, you had a bunch of people on the email
that probably didn't need to be there, and didn't have a few that should.
I've adjusted in this response.

This was introduced in change dce143c3381c355ef73be3dd97cf3ca1b15359b8,
you should add a "Fixes:" in the commit text.

I'll let the people that did this code comment, just to be sure, and
wait for
a v2 patch from you after that.

Thanks,
