    That will likely trigger anytime a hard nfs/cifs mount loses its
    server for 120s. To make this work you would need a new
    TASK_UNINTERRUPTIBLE_EXTERNAL_EVENT or similar and mark
    all the places which depend on those.

    I've also seen kernel modules that use semaphores like wait queues
    While that gives a little funny results (high load average) it worked
    so far, until this patch.
