Ah, I think I got my wires crossed. Mike's patch should land in for-next. It fixes one of his earlier patches that Doug pulled in. Can you just apply this there or do you want me to re-send? My patch can still go to -rc though. -Denny

I'll take Michael's patch, to for-next, but the other one needs a better commit message. You can't fix 'theoretical bugs' in -stable. Jason

Will drop the stable tag and touch up commit message and it can just go to for-next. As you said it's a theoretical bug. -Denny
