Liping Zhang 03e5fd0e9b netfilter: nft_set_rbtree: use per-set rwlock to improve the scalability ... Karel Rericha reported that in his test case, ICMP packets going through boxes had normally about 5ms latency. But when running nft, actually listing the sets with interval flags, latency would go up to 30-100ms. This was observed when router throughput is from 600Mbps to 2Gbps. This is because we use a single global spinlock to protect the whole rbtree sets, so "dumping sets" will race with the "key lookup" inevitably. But actually they are all _readers_, so it's ok to convert the spinlock to rwlock to avoid competition between them. Also use per-set rwlock since each set is independent.
