commit 4f47ccec30c21401c1e2c7349f8bac2787eaf67a
Author: Sven Eckelmann sven@narfation.org

batman-adv: Allow to disable debugfs support
The files provided by batman-adv via debugfs are currently converted to
    netlink. Tools which are not yet converted to use the netlink interface may
    still rely on the old debugfs files. But systems which already upgraded
    their tools can save some space by disabling this feature. The default
    configuration of batman-adv on amd64 can reduce the size of the module by
    around 11% when this feature is disabled.
