netfilter: ipset: fix race condition between swap/destroy and kernel side add/del/test v3
Florian Westphal pointed out that all netfilter hooks run with rcu_read_lock() held and em_ipset.c wraps the entire ip_set_test() in rcu read lock/unlock pair. So there's no need to extend the rcu read locked area in ipset itself. Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>
