The following commit has been merged in the master branch: commit 70396745fc1ad976809250f8e8b06162686fbb6b Author: Sven Eckelmann sven@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.
