From 4a27096bbe2cad4c6e78802a0d9dfe0e598a1129 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Fri, 26 Jun 2009 10:45:53 +0000 Subject: mac80211: Use rcu_barrier() on unload. The mac80211 module uses rcu_call() thus it should use rcu_barrier() on module unload. The rcu_barrier() is placed in mech.c ieee80211_stop_mesh() which is invoked from ieee80211_stop() in case vif.type == NL80211_IFTYPE_MESH_POINT. Acked-by: Paul E.
