And have you identified them and gotten a sign-off from those copyright
holders? I don't see that here documented at all, so I imagine you
documented it somewhere else? If so, where?

> - We want to maintain one hpilo driver between Linux and OpenBSD, and dual-licensing of hpilo driver's existing codebase and all the future bug fixes are the requirements for it. Therefore, we requested all other copyright owners of Linux hpilo driver to accept dual-licensing (MIT/GPL-2.0) for their respective contributions.

You can request, you can not require, right?

How are you going to deal with the fact that the driver really can not
be shared between these two operating systems without a lot of rewriting
and changing of the code?

Also, this code uses GPL-only symbols out of the Linux kernel, how are
you going to handle them in openbsd? Do you have a port of the code to
openbsd somewhere for review that shows how this all is translated?

And this is really a tiny driver, why not just rewrite it from scratch
for openbsd anyway? Odds are that's going to be required to fit into
the openbsd driver and coding style, right?

thanks,

greg k-h
