Can you construct a small C program to demonstrate the problem
without including any real kernel headers?
e.g. some thing like:
#define KERNEL_DEBUG "\001" "7"
void foo(void)
{
printk(KERN_DEBUG "%s: .....", ...);
}
Obviously, my test case is not a complete one. It is not
even valid C. It just show you some idea how a test case
can be constructed.
Once you have a small test case, it is much easier
to discuss and debug what is going on there.
BTW, how do you print the "string->data"? It helps to show the
functions that does the print.
