Ah, great. Thanks, Ian. The Reference Count Checking page is good information. There is a bunch of interest in doing better QC so this stuff is good to know. So in this case, it's probably difficult to assign a Fixes tag and that's fine. Whatever. But I'm not a huge fan of the "Leave off the Fixes tag" approach to preventing backports. There should be a better system for that. Maybe there should be a tag for that? Or possibly that's too complicated... I'm not sure. Anyway, let's leave it for now. If it's really a problem then we'll run into it again later and we can think about it at that point. regards, dan carpenter
