[PATCH net-next V2 0/2] mlx5: Use NUMA distance metrics

[Tariq Toukan]

Hi,

Expose the scheduler's sched_numa_find_closest() function, and use it in
mlx5 device driver.  This replaces the binary NUMA preference (local /
remote) with an improved one that minds the actual distances, so that
remote NUMAs with short distance are preferred over farther ones.

This has significant performance implications when using NUMA-aware
memory allocations, improving the throughput and CPU utilization.

Regards,
Tariq
