    vfio-ccw: add some logging · 60e05d1c
    Cornelia Huck authored
    Usually, the common I/O layer logs various things into the s390
    cio debug feature, which has been very helpful in the past when
    looking at crash dumps. As vfio-ccw devices unbind from the
    standard I/O subchannel driver, we lose some information there.
    
    Let's introduce some vfio-ccw debug features and log some things
    there. (Unfortunately we cannot reuse the cio debug feature from
    a module.)
