> Subject: [PATCH v7 0/5] vhost: handle memory hotplug for async vhost
> 
> When the guest memory is hotplugged, the vhost application which
> enables DMA acceleration must stop DMA transfers before the vhost
> re-maps the guest memory.
> 
> This patch set is to provide an unsafe API to drain inflight pkts
> which are submitted to DMA engine in vhost async data path, and
> notify the vhost application of stopping DMA transfers. And enable it
> in vhost example.
