The following commit has been merged in the master branch: commit 438b3d3fae4346a49fe12fa7cc1dc9327f006a91 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Mar 3 19:25:26 2019 +0100 batman-adv: Fix genl notification for throughput_override The throughput_override sysfs file is not below the meshif but below a hardif. The kobj has therefore not a pointer which can be used to find the batadv_priv data. The pointer stored in the hardif object must be used instead to find the correct meshif private data.
