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 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 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 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.
