Keith,
> The block integrity subsystem knows how to construct protection
> information buffers with metadata beyond the protection information
> fields. Remove the driver restriction.
>
> Note, this can only work if the PI field appears first in the metadata,
> as the integrity subsystem doesn't calculate guard tags on preceding
> metadata.
