From 75de9113bb9dc4939a7cd54e4bdfad555b35f5b1 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 14 Dec 2012 14:56:03 +0100 Subject: mac80211: optimise AP stop RCU handling If there are VLANs, stopping an AP is inefficient as it calls rcu_barrier() once for each interface (the VLANs and the AP itself). Optimise this by moving rcu_barrier() out of the station cleanups and calling it only once for all interfaces combined.
