This two-patch series introduces load-acquire/store-release barriers

For most contemporary architectures, this is more effective than a
SPSC ring based on smp_{r,w,}mb() barriers. More importantly,
load-acquire/store-release semantics make the ring code easier to
follow.

Here is the summary with links:
  - [bpf-next,v2,1/2] xsk: update rings for load-acquire/store-release barriers

You are awesome, thank you!
