From f3d4650015301d1c880df4523f7e7ef320a38aab Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 16 May 2014 13:22:52 -0400 Subject: cgroup: convert cgroup_has_live_children() into css_has_online_children() Now that cgroup liveliness and css onliness are the same state, convert cgroup_has_live_children() into css_has_online_children() so that it can be used for actual csses too. The function now uses css_for_each_child() for iteration and is published.
