A zero-initialization is fine, I sent a v2 with zero-initialization fixed yesterday: https://lkml.kernel.org/r/20250812-iot_iter_folio-v2-1-f99423309478@codewreck.org (and I'll send a v3 with the goto replaced with a bigger if later today as per David's request) I assume Andrew will pick it up eventually? -- Dominique Martinet | Asmadeus
