  hw/xen: do not set is_external=true on evtchn fds
  xen-block: implement BlockDevOps->drained_begin()
  block: drain from main loop thread in bdrv_co_yield_to_drain()
  block: add blk_in_drain() API
  hw/xen: do not use aio_set_fd_handler(is_external=true) in xen_xenstore
  block/export: stop using is_external in vhost-user-blk server
  block/export: wait for vhost-user-blk requests when draining
  util/vhost-user-server: rename refcount to in_flight counter
  virtio-scsi: stop using aio_disable_external() during unplug
  virtio-scsi: avoid race between unplug and transport event
