For any structure that crosses the user/kernel boundry, you _HAVE_ to
use the "__" variant. So for here you would use __u8 instead of
"unsigned char" in order for things to work properly.
I'm guessing you didn't test this all out on a mixed 32/64 bit system?
Please fix up and test to ensure that it all works properly before
resubmitting.
