I forgot about that. And similar for the next patch. But how do you
propose that I attribute the reporters and CoverityScan? Crap, it
would have been so much easier if the series was just pulled they

Greg, how do you want to play this? Can you perhaps update the fixes
tag here and in 12/12 if/when you apply the series?
