-Subject: [PATCH 64/96] net_sched/codel: do not defer queue length update
-
-When codel wants to drop last packet in ->dequeue() it cannot call
-qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
-about zero qlen and HTB/HFSC will deactivate class. The same class will
-be deactivated second time by caller of ->dequeue(). Currently codel and
-fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
-but there is no active classes.
-
-This patch update parent queue length immediately: just temporary increase
-qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
-if we have skb to return.
-
-This might open another problem in HFSC - now operation peek could fail and
-deactivate parent class.
