The following commit has been merged in the batadv/lts/5.15 branch: commit 0cac1c84e1ccdd71924c644f83e24f5ef47d6f7c Author: Sebastian Andrzej Siewior bigeasy@linutronix.de Date: Tue Jul 19 18:08:12 2022 +0200

batman-adv: Use netif_rx_any_context() any.

This reverts the stable commit e65d78b12fbc0 ("batman-adv: Use netif_rx().")

The commit message says:

| Since commit | baebdf48c3600 ("net: dev: Makes sure netif_rx() can be invoked in any context.") | | the function netif_rx() can be used in preemptible/thread context as | well as in interrupt context.

This commit (baebdf48c3600) has not been backported to the 5.15 stable series and therefore, the commit which builds upon it, must not be backported either.

Revert the backport and use netif_rx_any_context() again.
