Subject: [PATCH 02/20] batman-adv: Prefix bat_debugfs non-static functions with batadv_
From: Sven Eckelmann <sven@...fation.org>
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.
