The following commit has been merged in the master branch:
commit d98966173213704873864c4e5057d823996ae95d
Author: Antonio Quartulli <antonio at open-mesh.com>
Date:   Wed Apr 17 17:44:43 2013 +0200

    batman-adv: move batadv_slide_own_bcast_window to bat_iv_ogm.c
    
    batadv_slide_own_bcast_window() is used only in bat_iv_ogm.c
    and it is currently touching only batman_iv specific
    attributes.
    
    Move it into bat_iv_ogm.c and make it static.
