Subject: Re: [PATCH v2] perf unwind: Fix map reference counts

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
