Expand description

Miroir brut #[repr(C)] de struct statx (256 octets, cf. linux/stat.h).

Contrairement à StatxResult (forme décodée, indépendante de l’ABI), ce type est le tampon de sortie écrit directement par le kernel : io_uring’s IORING_OP_STATX y dépose les métadonnées de façon asynchrone. Les champs portent les noms kernel (zone d’interface, ADR-029). Construire via Statx::default (zéro-initialisé) avant de le confier au ring.
