Could you have close look at the tree to confirm if we have more spots where rcu_read_lock is unnecessary? $ git grep rcu_read_lock net/netfilter/ | wc -l 158 $ git grep rcu_read_lock net/ipv4/netfilter/ | wc -l 3 $ git grep rcu_read_lock net/ipv6/netfilter/ | wc -l 2 $ git grep rcu_read_lock net/bridge/netfilter/ | wc -l It's a fair good amount, it would take me around one hour probably to evaluate those here. If you can help us on verifying this, it would be simply great.
