From d0ec4230a077521a984ac604acbd8c15cc12a664 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 5 Aug 2015 16:03:19 -0400 Subject: [PATCH] cgroup: export cgrp_dfl_root While cgroup subsystems can't be modules, blkcg supports dynamically loadable policies which interact with cgroup core. Export cgrp_dfl_root so that cgroup_on_dfl() can be used in those modules.
