Subject: Re: [dpdk-dev] [PATCH v8 00/13] vhost packed ring performance optimization
Date: Thu, 24 Oct 2019 08:49:39 +0200 [thread overview]
Message-ID: <e84032fc-ae95-a28f-d3d0-15209a0d1ac9@redhat.com> (raw)
In-Reply-To: <20191021220813.55236-1-yong.liu@intel.com>
I get some checkpatch warnings, and build fails with clang.
Could you please fix these issues and send v9?
Thanks,
Maxime
