I can do tomorrow, thanks. I will re-post as RFC again because it will
depend on the cleanup part that was merged into Greg's tree - and thus
the series isn't standalone (and I'll mention that in the cover
message.)
We need to hear your concerns, which sounded quite damning for the
series, so that if it's possible to save this a plan to address your
concerns can be formulated.
Thanks.
