I'll try to look through the series later, but this email was marked as spam for me. And it seems to be due to all your emails failing DMARC, even though the others came through: dmarc=fail (p=NONE sp=NONE dis=NONE) header.from=kernel.org there's no DKIM signature at all, looks like you never went through the kernel.org smtp servers.

Yep, thanks for flagging, I guess I'll need to go read Konstantin's instructions and adjust my git send-email workflow. > > Linus
