[Qemu-devel] [PATCH v4 02/17] dataplane/virtio-blk: check exit conditions before aio_poll()

[Stefan Hajnoczi <stefanha@redhat.com>]

Check exit conditions before entering blocking aio_poll().  This is
mainly for consistency since it's unlikely that we are stopping in the
first event loop iteration.
