Subject: [dpdk-dev] [PATCH v2 4/6] vhost: log vring desc buffer changes
Date: Thu, 17 Dec 2015 11:11:59 +0800	[thread overview]
Message-ID: <1450321921-27799-5-git-send-email-yuanhan.liu@linux.intel.com> (raw)
In-Reply-To: <1450321921-27799-1-git-send-email-yuanhan.liu@linux.intel.com>

Every time we copy a buf to vring desc, we need to log it.
