Subject: [RFC PATCH V7 3/7] nvme: trace: put cid with le16_to_cpu()
Date: Fri, 7 Jun 2019 04:45:08 +0900 [thread overview]
Message-ID: <20190606194512.11020-4-minwoo.im.dev@gmail.com> (raw)
In-Reply-To: <20190606194512.11020-1-minwoo.im.dev@gmail.com>
The CID(Command Identifier) is in 16bits so that we need to convert it
to cpu's one.
