From d07c7cf49ae7c488e778c4d668f4cc10bd2fa971 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 14 May 2011 11:04:51 +0200 Subject: [PATCH] mac80211: add missing rcu_barrier mac80211 uses call_rcu() with functions that are defined in the module, so it must use rcu_barrier() at module exit time. Luckily, this seems to not be a problem in practice as module unload and unregistration takes a long time and probably does multiple synchronize_rcu().
