> I'm covering for Tony this week maintaining this tree.  He let me know there were a few patches you had to send Ivan and I was waiting on this one.  If I'm following correctly, this one will be dropped and the other ones are ready to be sent now to net then?

Yes, this one is beaten and the net tree already contains it[0].
There are still 3 Ivan's fixes not applied yet:
 * [1]
 * [2]
 * [3]

I'm wondering if it's worth to pass them through dev-queue since
they're urgent and have been tested already in 2 companies? They
could go directly to -net and make it into RC1.
