I figured as much.

Can you please point me to a specific place in the source code where I can
learn about kq filters, and maybe even show me "the old way and the new
way" next to each other for comparison?

I've managed to unbreak couple of the problems but now Im stuck on

nvidia_ctl.c:86: warning: 'struct dev_poll_args' declared inside parameter
list

Thanks,
