    cgroup: rename cgroup_subsys->base_cftypes to ->legacy_cftypes · 5577964e
    Tejun Heo authored
    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.
