ima_post_path_mknod() is currently enabled whether or not
CONFIG_SECURITY_PATH is enabled. Now it will only be enabled when
CONFIG_SECURITY_PATH is confiured. Changes like this need to be

Instead of creating separate IMA and EVM LSMs, the hooks are being
added to "integrity". Some sort of (brief) explanation should be
