    Subject[patch 01/34] cio: fix ineffective verify event
    From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>

    Path verification events occurring for offline devices are currently
    ignored. As a result, offline devices are not removed, even though
    they might no longer be accessible (for example because the last path
    to the device was varied offline). Fix this by scheduling a status
    evaluation for the affected subchannel when a path verification event
    occurs.
