netfilter: xt_hashlimit: RCU conversion xt_hashlimit uses a central lock per hash table and suffers from contention on some workloads. (Multiqueue NIC or if RPS is enabled) After RCU conversion, central lock is only used when a writer wants to add or delete an entry. For 'readers', updating an existing entry, they use an individual lock per entry. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
