Hi devvrat,
i can't understand exactly what you need to do, but maybe a solution can be
this: make a global simbol (i.e. a function pointer) that the kernel
should export.
so, there must be a kernel implementation of that function (also emtpy)
and a module implementation that could reassign as you like.
few steps,
kernel side:
void* foo_pointer;
EXPORT_SYMBOL( foo_pointer );
foo_pointer = empty_func;
void empty_func(void){};
module side:
include <somthing>
foo_pointer = something_other;
void something_other(void) {
// a lot of code... :P
}
could it works?
bye!
