From 85a9994a0a6cba1a6cc6af4bd3ebd85f778be0fe Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Thu, 12 May 2011 16:28:29 +0300 Subject: cfg80211/mac80211: avoid bounce back mac->cfg->mac on sched_scan_stopped When sched_scan_stopped was called by the driver, mac80211 calls cfg80211, which in turn was calling mac80211 back with a flag "driver_initiated". This flag was used so that mac80211 would do the necessary cleanup but would not call the driver. This was enough to prevent the bounce back between the driver and mac80211, but not between mac80211 and cfg80211. To fix this, we now do the cleanup in mac80211 before calling cfg80211. To help with locking issues, the workqueue was moved from cfg80211 to mac80211. Reported-by: Johannes Berg Signed-off-by: Luciano Coelho Signed-off-by: John W.
