s390/zcrypt: fix card and queue total counter wrap
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. Signed-off-by: Harald Freudenberger <freude@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
