Sorry, this is a little bit off-topic. But how does sysbot figure out the subsystems (like "[batman?]"). Because neither the reproducer nor the backtrace nor the console output mention anything batman-adv related.

Syzbot looks at several crash reports to determine the bug subsystems and in this case one of those crashes was pointing to net/batman-adv/multicast.c:
