> Subject: [PATCH v2 1/1] vhost: fix iotlb mempool single-consumer flag
>
> Bugzilla bug: 523
>
> Control thread (which handles iotlb msg) and forwarding
> thread both use iotlb to translate address. The former may modify the
> same entry of mempool and may cause a loop in iotlb_pending_entries
> list.
