Re: [PATCH] virtio_net/virtio_ring: fix race in enable_cb

Are you seeing the "Unlikely: restart svq failed" message in the logs?  If 
not, I don't think it can be this race.

No, I dont see the message, but this message only happens for guest->host 
traffic in the xmit function. I was fixing the poll function - which has no 
printk.
I added the disable_cb in the xmit function only  to adopt to changed 
enable_cb semantics.

I double checked my theory with a printk in enable_cb. The more_used check 
was true several times for the receiving virtqueue.
