-Subject: [PATCH] fq_codel: fix memory limitation drift
-
-memory_usage must be decreased in dequeue_func(), not in
-fq_codel_dequeue(), otherwise packets dropped by Codel algo
-are missing this decrease.
-
-Also we need to clear memory_usage in fq_codel_reset()
-
-Fixes: 95b58430abe7 ("fq_codel: add memory limitation per queue")
