Also, I almost hate to ask this, but why in the world are you creating
sysfs binary files?  I really don't think you should be doing this, as
those are only for firmware and other "pass-through" things the kernel
uses to have userspace talk directly to hardware.

Odds are you can remove these files, and use the "correct" user/kernel
interface which will result in much better speed and handle things
properly for you, instead of abusing this interface.

Unless you really are talking directly to hardware, in which case, I'm
kind of interested to see what you are doing here, so the source code
would be greatly appreciated.

thanks,
