I'll do that next time. My worries were just that the
'read_index_from()' API is broken with split index, which is what this
series fixes. It would be easy to introduce new breakages if we're

Thanks! As mentioned there's one call that was added that the evil
merge didn't get quite right, for which I sent the diff below in my
previous email. But I'm happy to fix that on top once this series
goes to master or next if that's preferred.
