Most of the symbols start with counter_, which is good. But a handful do not. Also, symbols called signal_* make my head spin - Linux already has a firmly ingrained notion of what a signal is, and this ain't it ;) Although the kernel tends to use sig_ for signals-as-an-IPC-thing. Also, many many drivers deal with signals-as-an-electrical-thing - is it appropriate for this particular driver to take that namespace?
