The following commit has been merged in the master branch: commit 70ea5cee95479695a5a84c0ef665604fdf1f8362 Author: Sven Eckelmann sven@narfation.org Date: Wed Jul 27 12:31:08 2016 +0200

batman-adv: Use proper name for gateway list head

The batman-adv codebase is using "list" for the list node (prev/next) and <list content descriptor>+"_list" for the head of a list. Not using this naming scheme can up in confusions when reading the code.
