Hello all

i wrote a LSM module and i want to register the security_operations after building it as a module. But when i try to compile the make prompts me a message:

WARNING: "register_security" .... undefined!

What is wrong?

This is my .config file for the kernel, section security:
CONFIG_KEYS=y
CONFIG_KEYS_DEBUG_PROC_KEYS=y
CONFIG_SECURITY=y
CONFIG_SECURITY_NETWORK=y
# CONFIG_SECURITY_NETWORK_XFRM is not set
CONFIG_SECURITY_FILE_CAPABILITIES=y
# CONFIG_SECURITY_ROOTPLUG is not set
CONFIG_SECURITY_DEFAULT_MMAP_MIN_ADDR=65536
# CONFIG_SECURITY_SELINUX is not set
