Take a look into criu/include/compiler.h please

#define NORETURN 		__attribute__((__noreturn__))
#define __packed 		__attribute__((__packed__))
#define __used 			__attribute__((__used__))
#define __maybe_unused 		__attribute__((unused))
#define __always_unused 	__attribute__((unused))

I think you better put __maybe_unused here.
