[RFC 0/3] virtio: NUMA-aware memory allocation
These patches are not ready to be merged because I was unable to measure a
performance improvement. I'm publishing them so they are archived in case
someone picks up this work again in the future.
The goal of these patches is to allocate virtqueues and driver state from the
device's NUMA node for optimal memory access latency. Only guests with a vNUMA
topology and virtio devices spread
