Subject: [RFC v2 05/13] vdpa: Pass the netlink attributes to ops.dev_add()
Date: Tue, 22 Dec 2020 22:52:13 +0800 [thread overview]
Message-ID: <20201222145221.711-6-xieyongji@bytedance.com> (raw)
In-Reply-To: <20201222145221.711-1-xieyongji@bytedance.com>
Pass the netlink attributes to ops.dev_add() so that we
could get some device specific attributes when creating
a vdpa device.
Signed-off-by: Xie Yongji <xieyongji@bytedance.com>
