Subject: [PATCHv2 5/5] mac80211_hwsim: Make sure beacon_timer gets deleted
Date: Thu, 30 Oct 2008 16:59:25 +0200	[thread overview]
Message-ID: <20081030150254.961883544@localhost> (raw)
In-Reply-To: 20081030145920.233178987@localhost

It was possible to trigger a kernel panic because beacon_timer may not
have been deleted in all cases when the kernel module was removed while
hostapd was still running.
