Which ioctl can be used for this?

I mean we can introduce a new ioctl for that in the future.

Ok, I see.

I wonder if it's better to do something similar to ccw:

1) requires the userspace to update the status bit in the response
2) update the dev->status to the status in the response if no timeout

Then userspace could then set NEEDS_RESET if necessary.

But NEEDS_RESET does not only happen in this case.

Yes, so you need an ioctl for userspace to update the device status
(NEEDS_RESET) probably.

Yes, but I'd like to do that after the initial version is merged since
NEEDS_RESET is not supported now.

Right.

Thanks
