batman-adv: fix global protection fault during soft_iface destruction
batadv_mesh_free() schedules some RCU callbacks which need the bat_priv struct to do their jobs, while free_netdev(), which is called immediately after, is destroying the private data. Put an rcu_barrier() in the middle so that free_netdev() is invoked only after all the callbacks returned. This bug has been introduced by ab8f433dd39be94e8617cff2dfe9f7eca162eb15 ("batman-adv: Move deinitialization of soft-interface to destructor") Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: David S.
