- have an RFC for QEMU that contains a provisional update of the
  relevant vfio headers so that we can discuss the QEMU side (and maybe
  shoot down any potential problems in the uapi before they are merged
  in the kernel)

This qemu patch is linked in the cover letter.

The QEMU changes need to be discussed on qemu-devel, a link to a git
tree with work in progress only goes so far.

Of course, but we are not going to bother the qemu community until the
kernel side is settled.

(From my quick look there, this needs to have any headers changes split
out into a separate patch. The changes in migration.c are hard to
review; is there any chance to split the error path cleanups from the
interface changes?)

We can do whatever, once we figure out what it actually needs to look
like. Rip and replace might be the best option.
