IIUC, regzbot might not notice because the patch lacks a Link: tag
to the original regression report. The Link tag is to Jan's patch
that was posted sometime in April, I think, which also lacks the
Link tag to the original report of the regression which did not
happen until May 4. If regzbot is smart enough to notice that the
patch also has a Fixes: tag for the commit that was identified as
bad in the original regression report, then I expect regzbot will
find it.

Best regards,

Hey, I see the patch hit linux-next and regzbot noticed and
now lists the patch as an incoming fix. Great job with regzbot!

By the way, I think regzbot is a great idea, and I think any resources
devoted to develop it more would pay handsome returns for the
quality of Linux. If no one but you is working on it, I actually might
be willing to volunteer some time to help you develop it.

Best regards,

Chuck
