[RFC PATCH v1 0/2] virtio_net: Better low memory handling.
The following series applies to net-next.
The following series changes the low memory paths in virtio_net to allow
the driver to contribute to reclaim when memory is tight.
It attempts to rectify some performance problems we've seen where the
network performance drops significantly when memory is low. The working
theory is that while the driver contributes to memory pressure when
throughput
