>     
>     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.

> 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.
