include/linux/device.h:
static inline int dev_to_node(struct device *dev)
{
return dev->numa_node;
}
struct device {
.....
int numa_node; /* NUMA node this device is close to */
...
};
In case when there are two nodes and only node 0 has memory,
dev->numa_node will be 0 even though the device will be connected to the
pci root port of node 1.
