Currently xen-block uses an IOThread to handle AIO but the event channels
are dealt with on QEMU's main thread. This series allows them to be
dealt with in the same context.

Paul Durrant (3):
  xen-bus: use a separate fd for each event channel
  xen-bus: allow AioContext to be specified for each event channel
  xen-bus / xen-block: add support for event channel polling
