Subject: [PATCH 2/9] nvme/core: add some more values from the spec
Date:   Tue, 19 Mar 2019 16:41:09 +0200
Message-Id: <20190319144116.400-3-mlevitsk@redhat.com>
In-Reply-To: <20190319144116.400-1-mlevitsk@redhat.com>
References: <20190319144116.400-1-mlevitsk@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds few defines from the spec,
that will be used in the nvme-mdev driver
