Yes, I'm getting some syzbot warnings as well now. I had however only planned to get this in linux-next, since that is what the syzbot mails were complaining about, but I see this got into -rc5... It's honestly just a warn on something that would fail anyway so I'd rather let it live in -next first, I don't get why syzbot is so verbose about this - it sent a mail when it found a c repro and one more once it bisected the commit yesterday but it should not be sending more? (likewise it should pick up the fix tag even if it only gets in -next, or would it keep being noisy unless this gets merged to mainline?) FWIW this is along with the 5 other patches I have queued for 5.9 waiting for my tests as my infra is still down, I've stopped trying to make promises, but I could push at least just this one to -next if that really helps. Sorry for that, things should be smoother once I've taken the time to put things back in place. -- Dominique
