vringh_test hangs on __vring_new_virtqueue() because `vqs_list_lock`
is not initialized.
Let's initialize it before call __vring_new_virtqueue()

I wonder what's the reason for not having this in VDUSE_CREATE_DEV?

The code looks but I think it's not a must since each kobject could be

This patch allows device features to be provisioned via vdpa. This
will be useful for preserving migration compatibility between source
and destination:
# vdpa dev add name dev1 mgmtdev pci/:02:00.0 device_features 0x30002
# dev1: mac 52:54:00:12:34:56 link up link_announce false mtu 65535
Set the preferred color depth to 24 bits and the fbdev bpp to 32
bits. This will signal XRGB as default format to clients.

Set the preferred depth from the format of the scanout buffer. The
value cannot be hardcoded, as the scanout buffer's is only known at
runtime. Also derive the fbdev emulations bpp value from the scanout
format.

Cirrus has a preferred color depth of 16 bit; also use it as fbdev
bpp value. Don't use the color depth directly. It has a different
meaning than bpp and both cannot be used interchangeably.

If no preferred value for bits-per-pixel has been given, fall back
to 32. Never use the preferred depth. The color depth is the number
of color/alpha bits per pixel, while bpp is the overall number of
bits in most cases.
Most noteworthy, XRGB has a depth of 24 and a bpp value of 32.
Using dept
Logicvc can have different values for the preferred color depth. Set
the fbdev bpp value depending on the runtime value.

Set the preferred depth from the format of the scanout buffer. The
value cannot be hardcoded, as the scanout buffer's is only known at
runtime. Keeping the existing switch statement just duplicates the
driver's existing logic for format detection.
Also remove the FIXME comment from the call to drm
A number of drivers mix up the meaning of bits-per-pixel and color
depth. For each of them, set the correct values. As a rule of thumb,
the color depth is the number of color and alpha bits that affect
image composition. The bpp value is the color depth in the pixel
plus the filler bits.
The color
Set the preferred color depth to 24 bits and the fbdev bpp to 32
bits. This will signal XRGB as default format to clients.

Sorry; things keep getting in the way of finishing this :/
As such, I need a bit of time to get on-track again..
