From b36824c75c7855585d6476eef2b234f6e0e68872 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 22 Nov 2013 18:20:44 -0500 Subject: cgroup: unexport cgroup_css() and remove __file_cft() Now that cgroup_event is made memcg specific, the temporarily exported functions are no longer necessary. Unexport cgroup_css() and remove __file_cft() which doesn't have any user left. Signed-off-by: Tejun Heo Acked-by: Li Zefan Acked-by: Kirill A.
