SubjectError Communicating With Module
	Hello, first of all I must tell you that I do not belong to this
mailing list as of yet, so, please respond to me via brush@cse.unl.edu.
Thank you very much in advance!

My problem is as follows:

I have added a variable named bens_variable to ksyms.c as follows:

extern int bens_variable=10;
I have then exported the variable in ksyms.c as follows:

EXPORT_SYMBOL(bens_variable);
I then recompiled the kernel as bzImage and everything went
perfectly fine. I then wrote a module for that particular kernel which
is simple and looks as follows:

#define MODULE
#define __KERNEL__
#include <linux/module.h>

int init_module(void){
printk(bens_variable);
return 0;
}
void cleanup_module(void){
printk("<1>Module Unloaded\n");
}
But, of course, whenever I try and compile the module to load it
using gcc it tells me that bens_variable is undefined - which makes sense,
however I don't see how I can compile this without typing in

extern int bens_variable;
again. How do I get my module to compile and print out the value
of bens_variable as defined within ksyms.c?

Again, please respond to me via brush@cse.unl.edu. Thanks again in
advance!!!
