[PATCH v5 00/24] deprecate rte_atomic functions

[Stephen Hemminger]

The rte_atomicNN_* family was flagged for deprecation in 2021 by
commit 3ec965b6de12 ("doc: update atomic operation deprecation")
but enforcement never landed and in-tree usage continued to grow.

This series finishes converting every remaining in-tree caller to
the C11-style rte_atomic_*_explicit() / RTE_ATOMIC() API, then
marks the legacy functions __rte_deprecated so future in-tree and
out-of-tree uses are caught at compile time.

The goal of this series is to get driver writers to review and
test each change.

v5 - rebase now that ring changes are merged.
   - drop the barrier (rte_smp_mb) patch not required.


Stephen Hemminger (24):
  bpf: use C11 atomics in BPF_ST_ATOMIC_REG
  net/bonding: use stdatomic
  net/nbl: remove unused rte_atomic16 field
  net/ena: replace use of rte_atomicNN
  net/failsafe: convert to stdatomic
