From 5577964e64692e17cc498854b7e0833e6532cd64 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 15 Jul 2014 11:05:09 -0400 Subject: cgroup: rename cgroup_subsys->base_cftypes to ->legacy_cftypes Currently, cgroup_subsys->base_cftypes is used for both the unified default hierarchy and legacy ones and subsystems can mark each file with either CFTYPE_ONLY_ON_DFL or CFTYPE_INSANE if it has to appear only on one of them. This is quite hairy and error-prone. Also, we may end up exposing interface files to the default hierarchy without thinking it through. cgroup_subsys will grow two separate cftype arrays and apply each only on the hierarchies of the matching type. This will allow organizing cftypes in a lot clearer way and encourage subsystems to scrutinize the interface which is being exposed in the new default hierarchy. In preparation, this patch renames cgroup_subsys->base_cftypes to cgroup_subsys->legacy_cftypes. This patch is pure rename.
