-Subject: [PATCH] netfilter: flowtable: avoid possible false sharing
-
-The flowtable follows the same timeout approach as conntrack, use the
-same idiom as in cc16921351d8 ("netfilter: conntrack: avoid same-timeout
-update") but also include the fix provided by e37542ba111f ("netfilter:
-conntrack: avoid possible false sharing").
