From 51e4e7faba786d33e5e33f8776c5027a1c8d6fb7 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Wed, 12 Sep 2012 16:12:03 +0200 Subject: cgroup: net_prio: Do not define task_netpioidx() when not selected task_netprioidx() should not be defined in case the configuration is CONFIG_NETPRIO_CGROUP=n. The reason is that in a following patch the net_prio_subsys_id will only be defined if CONFIG_NETPRIO_CGROUP!=n. When net_prio is not built at all any callee should only get an empty task_netprioidx() without any references to net_prio_subsys_id.
