Subject: [PATCH] nvme: lightnvm: use nvme admin queue
Date: Fri, 20 Nov 2015 14:28:16 +0800 [thread overview]
Message-ID: <1448000896-4526-1-git-send-email-ww.tao0320@gmail.com> (raw)
According to Open-ChannelSSDInterfaceSpecification 0.1,
NVMe-NVM admin commands use vendor specific admin opcodes
of NVMe, so use the NVMe admin queue to dispatch these
commands
