net_sched: htb: do not acquire qdisc lock in dump operations
htb_dump() and htb_dump_class() do not strictly need to acquire qdisc lock to fetch qdisc and/or class parameters. We hold RTNL and no changes can occur. This reduces by 50% qdisc lock pressure while doing tc qdisc|class dump operations. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
