[PATCH] netfilter: Get rid of central rwlock in tcp conntracking TCP connection tracking suffers of huge contention on a global rwlock, used to protect tcp conntracking state. As each tcp conntrack state have no relations between each others, we can switch to fine grained lock, using a spinlock per "struct ip_ct_tcp" tcp_print_conntrack() dont need to lock anything to read ct->proto.tcp.state, so speedup /proc/net/ip_conntrack as well.
Thats an interesting test-case, but one lock per conntrack just for TCP tracking seems like overkill. We're trying to keep the conntrack stuctures as small as possible, so I'd prefer an array of spinlocks or something like that. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
