[RFC 00/32] remove rte_smp barrier functions

[Stephen Hemminger <stephen@networkplumber.org>]

This patch series completes the removal of rte_smp_XX barrier
functions that was announced over five years ago (20.05).

Most of this is mechanical with AI assistance, so strongly
encourage maintainers to take a good look.

Stephen Hemminger (32):
  bpf: replace deprecated SMP barriers with C11 fences
