Sorry guys.  I think my initial reply got lost.

Currently my approach was approved in code review.  The only hold up
seems to be time, and gregkh getting overloaded and dropping the
patches, for the Nth time.

So I need to resend.  I won't for a week or two because I am right in
the middle of moving.

Sorry I thought I had replied to the earlier question of status with
this but is seems that message got lost somewhere in the delivery
process.
