Is it safe to use it for driver's purposes when the driver owns the urb,
that is, starting from the completion routine until the urb is submitted
with usb_submit_urb()?
Right now, it should be.
In fact I'm not sure why it ever got called "private" to usbcore/hcds.
I thought the idea was that it should be like urb->status, reserved for
whoever controls the URB.
The documentation comment header block says:
/**
* struct urb - USB Request Block
* @urb_list: For use by current owner of the URB.
