From mboxrd@z Thu Jan 1 00:00:00 1970 From: Amit Shah Subject: [PATCH v2 0/2] virtio: console: add locking around control out-vq Date: Fri, 29 Mar 2013 16:30:06 +0530 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: virtualization-bounces@lists.linux-foundation.org Errors-To: virtualization-bounces@lists.linux-foundation.org To: Rusty Russell Cc: Amit Shah , Virtualization List List-Id: virtualization@lists.linuxfoundation.org The in-vq operations were protected by a lock, but the out-vq operations were not. This caused panics / errors as described in patch 2. Fix that. The first patch renames the existing cvq_lock to c_ivq_lock to match c_ivq. The second patch introduces the c_ovq_lock for the c_ovq. Please apply. I also believe this is a candidate for stable. v2: * Use spin_lock instead of spin_lock_irq. Pointed out by Wanlong Gao.
