I'd be very interested to know what else is needed after commit 98dc08bae678 ("fsverity: stop using PG_error to track error status") which is upstream now, and https://lore.kernel.org/linux-fsdevel/20221028224539.171818-1-ebiggers@kernel.org/T/#u ("fsverity: support for non-4K pages") which is planned for 6.3. - Eric
