This doesn't appear to be a math error like LU-9683, but possibly caused by NTP.
ptlrpc uses ktime_get_real() for timing events where other modules use ktime_get() for timing.
ktime_get_real() "can jump backwards due to a leap second update, NTP adjustment settimeofday() operation from user space."
