pkt_sched: move the sanity test in qdisc_list_add() The WARN_ON(root == &noop_qdisc)) added in qdisc_list_add() can trigger in normal conditions when devices are not up. It should be done only right before the list_add_tail() call. Fixes: e57a784d8cae4 ("pkt_sched: set root qdisc before change() in attach_default_qdiscs()") Reported-by: Valdis Kletnieks <Valdis.Kletnieks@vt.edu> Tested-by: Mirco Tischler <mt-ml@gmx.de> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
