From 033fa1c5f5f73833598a0beb022c0048fb769dad Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 19 Nov 2012 08:13:39 -0800 Subject: cgroup, cpuset: remove cgroup_subsys->post_clone() Currently CGRP_CPUSET_CLONE_CHILDREN triggers ->post_clone(). Now that clone_children is cpuset specific, there's no reason to have this rather odd option activation mechanism in cgroup core. cpuset can check the flag from its ->css_allocate() and take the necessary action. Move cpuset_post_clone() logic to the end of cpuset_css_alloc() and remove cgroup_subsys->post_clone(). Loosely based on Glauber's "generalize post_clone into post_create" patch.
