[NETFILTER]: nf_conntrack_expect: use RCU for expectation hash
Use RCU for expectation hash. This doesn't buy much for conntrack runtime performance, but allows to reduce the use of nf_conntrack_lock for /proc and nf_netlink_conntrack. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
