user_data: track things like get_user_data(&my_pointer);
The code here looks like:
void get_user_data(struct my_struct *p)
{
copy_from_user(p, user_pointer, sizeof(*p));
}
The old code tracked user pointer across functions but only if the data
was returned, not if it was passed back through a parameter.
