The following commit has been merged in the master branch: commit 920535afae409445e8e504012b7c61c755f1ed92 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 02:09:42 2012 +0200 batman-adv: Prefix main 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.

The following commit has been merged in the master branch: commit 8ed9d7a13fb4c57d911767bad6cc2addfd88a308 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 02:09:38 2012 +0200 batman-adv: Prefix soft-interface 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.

The following commit has been merged in the master branch: commit 8bad6dc4bd15cdd29fb76d94f24e5f44dd72cdcf Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 02:09:37 2012 +0200 batman-adv: Prefix send 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.

The following commit has been merged in the master branch: commit 217bc92c81951344d1466d08592b5beaee89c06f Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 02:09:35 2012 +0200 batman-adv: Prefix ring_buffer 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.

batman-adv; branch, master, updated. v2012.1.0-140-g3397fdd

The following commit has been merged in the master branch: commit 3397fdd9bf1d88bdadefde63719a9124f12fc7b9 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 02:09:33 2012 +0200 batman-adv: Prefix icmp-socket 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.
