From fd9a08a7b83074e34c13c6340f673f7a51f53489 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Thu, 25 Oct 2012 04:16:58 +0000 Subject: cgroup: net_cls: Pass in task to sock_update_classid() sock_update_classid() assumes that the update operation always are applied on the current task. sock_update_classid() needs to know on which tasks to work on in order to be able to migrate task between cgroups using the struct cgroup_subsys attach() callback.
