Hi!

Yes, I reported the bug against -next.

But: you are the last one to sign it off, so I assume committed it to
git, and you are the one to talk to about fixing it.

90fb702791bf99b959006972e8ee7bb4609f441b causes oops at boot for me.

So... I'm not git wizard, but... if I do log on v5.8, it is not in the
list, and if I do log on v5.9, it shows it.

So yes, I believe this in mainline.

Should I test v5.9 next? Or do you want me to test some patch?

Best regards,
