The following commit has been merged in the master branch: commit 0114926f0d99e69671e08d7f31935b6fc74dcfd8 Author: Sven Eckelmann <sven(a)narfation.org> Date: Wed May 16 20:23:16 2012 +0200 batman-adv: Prefix translation-table 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.
