Subject: [PATCH] net/9p/trans_virtio.c: add a terminal char for mount tag
Date: Wed, 1 Aug 2018 15:44:54 +0800	[thread overview]
Message-ID: <5B6164F6.60004@huawei.com> (raw)

chan->tag has no terminal char at last which will result in printing messy
code when debugging code. So we should add '\0' for tag.
