From 7907c7d33c3733b2265dadc6385fe028af72b4c7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 4 Dec 2013 23:47:09 +0100 Subject: mac80211: free all AP/VLAN keys at once When the AP interface is stopped, free all AP and VLAN keys at once to only require synchronize_net() once. Since that does synchronize_net(), also move two such calls into the function (using the new force_synchronize parameter) to avoid doing it twice.
