Note, this just showed up publically on August 12, where were you with
all of this new code before then? :)

For the in-kernel code, we would have to rip out all of the work you did
for all older kernels, so that's a non-starter right there.

As for what codebase to work off of, I don't want to say it is too late,
but really, this shows up from nowhere and we had to pick something so
we found the best we could at that point in time.

Is there anything specific in the codebase you have now, that is lacking
in the in-kernel code? Old-kernel-support doesn't count here, as we
don't care about that as it is not applicable. But functionality does
matter, what has been added here that we can make use of?

And do you have any "real" development history to look at instead of the
"one giant commit" of the initial code drop? That is where we could
actually learn what has changed over time. Your repo as-is shows none
of the interesting bits :(

thanks,

greg kh
