The following commit has been merged in the next branch: commit e0c233a34178c3db2a57912f19686d4f6851b3c6 Author: Sven Eckelmann sven@narfation.org Date: Sat May 12 02:09:41 2012 +0200

batman-adv: Prefix vis non-static functions with batadv_

batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.
