register_security — registers a security framework with the kernel
int register_security (struct security_operations * ops);
This function is to allow a security module to register itself with the
kernel security subsystem. Some rudimentary checking is done on the ops
value passed to this function. A call to unregister_security should be
done to remove this security_options structure from the kernel.
If there is already a security module registered with the kernel, an error will be returned. Otherwise 0 is returned on success.
