security_module_enable — Load given security module on boot ?
a pointer to the struct security_operations that is to be checked.
Each LSM must pass this method before registering its own operations to avoid security registration races. This method may also be used to check if your LSM is currently loaded during kernel initialization.
-The passed LSM is the one chosen by user at boot time, -or user didsn't specify a specific LSM and we're the first to ask for registeration permissoin, -or the passed LSM is currently loaded. Otherwise, return false.
