Thanks for the heads up.

I've pulled this, although I don't see the rdma fix in the rdma tree
(the pull for which is still pending in my inbox - I've merged a big
chunk already, people have been very good about sending their pulls
early - thanks)

Let's hope that gets handled soonish - but I'm adding Jason explicitly
to the cc just so that he sees this.

I'll take the fix directly in the worst case, but prefer for things to
go through the normal subsystem maintainer if at all possible, and
this one seems fairly straightforward.
