One-element arrays are being deprecated[1]. Replace the one-element arrays with a simple value type u8 reserved, once this is just a placeholder for alignment.
Also, while there, use the preferred form for passing a size of a struct. The alternative form where struct name is spelled out hurts readability and introduces an opportunity for a bug when the variable type is changed but the corresponding sizeof that is passed as argument is not.
