> xen-netfront: Rework the fix for Rx stall during OOM and network stress
>
> The commit 90c311b0eeea ("xen-netfront: Fix Rx stall during network
> stress and OOM") caused the refill timer to be triggerred almost on
> all invocations of xennet_alloc_rx_buffers for certain workloads.
> This reworks the fix by reverting to the old behaviour and taking into
> consideration the skb allocation failure. Refill timer is now triggered
> on insufficient requests or skb allocation failure.

> The above patch happens to fix one patch which has already been pushed as stable fix into 4.9.y stable tree (5d5c293af8348b540ef721d810f7549ac3ab81c2).

> Note to davem@: David, given that this is not a new patch, and not a patch from me, I decided to just fall into the default stable process, therefore, contacted stable@ directly. Let me know if you agree with this flow.
