Inizia eseguendo il comando cargo check riportato per x86_64-unknown-linux-gnux32 ed esamina le assertion in src/io_uring/mod.rs, src/check_types.rs e src/fs/constants.rs. Confronta i controlli di layout e dimensione che falliscono tra i target elencati. Il lavoro è completato quando il workspace compila con tutte le API e tutti i target per i target interessati.
