NACK. Greg's bot got to it but...

As per Greg's bot, no signed-off-by line.

Sorry for confusion, I wasn't meant to send this as a PATCH, but reporting the issue. The diff was just sent as reference to repro the bug, and I forgot to remove PATCH from the title. I apologize for the confusion.

Can you explain what the issue is? I don't get it.

I'll let Jeff explain from his perspective, but 99% the issue is as described in [0], i.e. not a bug.
