    s390/zcrypt: fix card and queue total counter wrap · fcd98d40
    Harald Freudenberger authored
    The internal statistic counters for the total number of
    requests processed per card and per queue used integers. So they do
    wrap after a rather huge amount of crypto requests processed. This
    patch introduces uint64 counters which should hold much longer but
    still may wrap. The sysfs attributes request_count for card and queue
    also used only %ld and now display the counter value with %llu.
    
    This is not a security relevant fix. The int overflow which happened
    is not in any way exploitable as a security breach.
