Subject: [PATCH] vhost_net: remove wrong 'unlikely' check
Date: Mon, 17 Jun 2019 16:50:29 +0800	[thread overview]
Message-ID: <20190617085029.21730-1-huhai@kylinos.cn> (raw)

Since commit f9611c43ab0d ("vhost-net: enable zerocopy tx by default")
experimental_zcopytx is set to true by default, so remove the unlikely check.
