Subject: [PATCH v2 0/2] virtio: console: add locking around control out-vq
Date: Fri, 29 Mar 2013 16:30:06 +0530 [thread overview]
Message-ID: <cover.1364554596.git.amit.shah@redhat.com> (raw)
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.
