The following commit has been merged in the master branch:
commit 5853e22c58b318232fd6e15033ccb0852f865c0b
Author: Sven Eckelmann <sven at narfation.org>
Date:   Sat May 12 02:09:24 2012 +0200

    batman-adv: Prefix bat_sysfs 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.
