The following commit has been merged in the master branch:
commit 3b300de322014f529b2e0a72a92c414686b85671
Author: Sven Eckelmann <sven at narfation.org>
Date:   Sat May 12 18:33:53 2012 +0200

    batman-adv: Prefix bridge_loop_avoidance local static functions with batadv_
    
    All non-static symbols of batman-adv were prefixed with batadv_ to avoid
    collisions with other symbols of the kernel. Other symbols of batman-adv
    should use the same prefix to keep the naming scheme consistent.
