The following commit has been merged in the master branch: commit 40a072d777a4f417c0296e06f91297b0f3f2fa36 Author: Sven Eckelmann sven@narfation.org Date: Sat May 12 02:09:23 2012 +0200
batman-adv: Prefix bat_debugfs 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.
