Subject: how to guard a kernel module

Hi, all
 I have a security related module , which is compiled as CONFIG_XYZ=m. And I want to monitor and guard it with LKRG, just as that LKRG guards SELinux and Seccomp.
I added some codes to LKRG , and wrapped them by #ifdef CONFIG_XYZ ... #endif, but this seemed to not work.
I also tried if(!strcmp(CONFIG_XYZ, "m")), but error occurred as "error: 'CONFIG_XYZ' undeclared (first use in this function);".
 Maybe this issue has little to do with LKRG, and I am sorry if bothering you. 
Any suggestion is very appreciated.
thanks and best regards,
Li Cheng
