From 1a8eaf0733ca754533a03d6cfa4463def2b81ce3 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 12 May 2012 02:09:32 +0200 Subject: batman-adv: Prefix hash 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.
