Thanks alot. It works.

Now another problem with versioning. It seems even after I have the
following in my module c file the symbol generated is not versioned:

#define MODULE
#include <linux/modversions.h>
#include <linux/kernel.h>

When I do nm on the module, fdbIoSwitchHook is still a pure name without
the version info. Can you please tell me how to enable the versioning
for the symbol fdbIoSwitchHook?

Appreciate your help!
