Subject: [PATCH net-next 0/4] u64_stats: Introduce u64_stats_copy()

On 64bit arches, struct u64_stats_sync is empty and provides no help
against load/store tearing. memcpy() should not be considered atomic
against u64 values. Use u64_stats_copy() instead.

David Yang (4):
  u64_stats: Introduce u64_stats_copy()
  net: bridge: mcast: fix memcpy with u64_stats
  macsec: fix memcpy with u64_stats
  vxlan: vnifilter: fix memcpy with u64_stats
