      # In [94d81c3c39e3ddc441c3af3f874e53b197cf3f54][0] rails upstream removed
      # the code that copied the values of
      # config.active_record.yaml_column_permitted_classes to
      # ActiveRecord.yaml_column_permitted_classes during the
      # config.after_initialize stage.
      #
      # We can not move the setting of
      # config.active_record.yaml_column_permitted_classes out of the
      # after_initialize because then the gitlab classes are not loaded yet
      #
      # This change was also ported to the 6.1 branch and released in 6.1.7.
      # Some distributions like Debian even [backported this change to
      # 6.1.6.1][1].
      #
      # This restores the code needed to have gitlab work in those cases.
