From 924f0d9a2078f49ff331bb43196ec5afadc16b8f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 13 Feb 2014 06:58:41 -0500 Subject: cgroup: drop @skip_css from cgroup_taskset_for_each() If !NULL, @skip_css makes cgroup_taskset_for_each() skip the matching css. The intention of the interface is to make it easy to skip css's (cgroup_subsys_states) which already match the migration target; however, this is entirely unnecessary as migration taskset doesn't include tasks which are already in the target cgroup. Drop @skip_css from cgroup_taskset_for_each().
