From 3da0495cf863288b6798e121ccf93c4453c6c768 Mon Sep 17 00:00:00 2001 From: Zefir Kurtisi Date: Fri, 13 Jul 2012 10:38:34 +0200 Subject: [PATCH] compat: fix system crash on 2.6.35 when flushing work Ubuntu 10.10 stock kernel (2.6.35-22-generic) crashes in compat_flush_scheduled_work(), that is called e.g. when mac80211 module is unloaded. The problem was introduced with 80bf8a83 compat: backport system work queues system_wq and system_long_wq The crash happens in compat_flush_scheduled_work() where both flush_workqueue() and flush_scheduled_work() are called successively. Removing one of them resolves the issue. All compat-wireless tarballs after 2012-03-18 are affected. Signed-off-by: Zefir Kurtisi Signed-off-by: Luis R.
