Seems like a reasonable approach. However, what I'd prefer to do is
make these changes as a separate set of changes on top of this patch
series rather than try to integrate them into the existing series.
If there are problems, that should make it more bisectable. Do you
have any concerns with such an approach?
Cheers,
Dave.
