[Qemu-devel] [PATCH 0/2] virtio: revert virtio_queue_set_notification() nesting |

The virtio_queue_set_notification() nesting introduced for AioContext polling
raised an assertion with virtio-net (even in non-polling mode). Converting
virtio-net and virtio-crypto to use virtio_queue_set_notification() in a
nesting fashion would be invasive and isn't worth it.
Patch 1 contains the revert to resolve the bug that Doug noticed.
Patch 2 is a less efficient but safe alternative.
Stefan Hajnoczi (2):
Revert "virtio: turn vq->notification into a nested counter"
virtio: disable notifications again after poll succeeded
