Subject: [dpdk-dev] [PATCH] vhost: fix dirty page logging missing
Date: Mon,  4 Nov 2019 19:15:47 +0800	[thread overview]
Message-ID: <20191104111547.54885-1-yong.liu@intel.com> (raw)

Packets data are directly copied when doing batch enqueue, add missed
dirty page logging after memory copy.

Fixes: ad3df6dcc0fc ("vhost: add packed ring batch enqueue")
