So I only queued this up for -stable, not Linus's tree. Paul has started the work of moving his patch upstream, so I suspect that if I queued this patch of our's up to my tree now it would land in Linus's tree about the same time :-) If something non-trivially stalls Paul's submission work, we can queue this up.
