That one already landed upstream w/ the deadline server changes:
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5d69eca542ee17c618f9a55da52191d5e28b435f

On this one, I wanted to get some more review of the chain-migration
logic before really pushing it.

I do agree this is more of a cleanup, but I also want to try to
refactor it a touch to try to consolidate the logic, so it's not quite
ready.

So I'm just submitting the set here for now to try to get the ball
rolling, but I'll continue working on the larger series and will pull
things down as they make sense.

thanks
