From a5e6a3b0222fb19eaae424226533eadb0be20e93 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 16 Mar 2017 12:53:42 +0200 Subject: [PATCH] net/sched: fq_codel: Avoid set-but-unused variable The code introduced by commit 2ccccf5fb43f ("net_sched: update hierarchical backlog too") only sets prev_backlog in fq_codel_dequeue() but not using that anywhere, remove that setting.
