For the record, I never wrote that. Not sure why you repeat this over this thread. And for the record, I don't share Jason's concern about proprietary userspace. From what I see, whoever is consuming the KAPI is free to do that however he pleases. But, this is completely distant from my concerns about this driver. [...] >> > I agree.

Sorry, but I have to say this is ridiculous argument, really Alex. Apples and oranges. [...]
