Hello Guo, I'm talking about kernel space. I want to get kernel space symbols when running a kernel module... Or maybe the linker can link agains the kernel (so the addresses of the symbols are statically inserted into my module, also), but that wouldn't be as good as getting the symbols dynamically.
