commit 21643310f1918758d22367ff5c81d34a49c3645d 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.
