Date: Wed,  9 Sep 2015 15:50:09 +0200	[thread overview]
Message-ID: <1441806613-13775-40-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1441806613-13775-1-git-send-email-pbonzini@redhat.com>

From: KONRAD Frederic <fred.konrad@greensocs.com>

This just removes spinlock as it is not used anymore.
