Oleg, I know you sent me a mbox with these patches, but I rather pull
the real email. But this is the only one I have. With a comment like
that, I wouldn't pull it in.
But as you sent me them to include them, I take it, this is ready.
Peter, Frederic, can you review these patches and ack or nack them?
Thanks,
-- Steve
