Thanks John, Shuah for sorting this out. I confess that I hadn't
noticed the conflict before proposing this for 6.2: in retrospect I
should've checked more carefully given the amount of churn in the
patch.

If we have to drop this patch and split the series, that's not a
problem: it's really just an example. But if the conflict's resolved,
that's even better.

Thanks again!
