Why do you think Red Hat, SUSE or any other distro vendor's engineers
should be made to review what amounts to be a massive dump of changes
you developed over years?

Presummably you have heard of "upstream first"!?  Why do you think it
doesn't apply to drbd?

It'd be one thing if drbd never went upstream but _it did_.  As is
your development model is completely wrong.
