  cgroup: rstat: use LOCK CMPXCHG in css_rstat_updated (2025-12-08 08:26:56 -1000)

----------------------------------------------------------------
cgroup: Fixes for v6.19-rc1

- Fix a race condition in css_rstat_updated() where CMPXCHG without LOCK
  prefix could cause lnode corruption when the flusher runs concurrently
  on another CPU. The issue was introduced in 6.17 and causes memcg stats
  to become corrupted in production.
