From 5ce2d488fe039ddd86a638496cf704df86c74eeb Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 8 Jul 2008 17:06:30 -0700 Subject: pkt_sched: Remove 'dev' member of struct Qdisc. It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument.
