From 021a17ed796b62383f7623f4fea73787abddad77 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Tue, 15 May 2018 16:24:37 +0200 Subject: pfifo_fast: drop unneeded additional lock on dequeue After the previous patch, for NOLOCK qdiscs, q->seqlock is always held when the dequeue() is invoked, we can drop any additional locking to protect such operation.
