Subject: Re: [PATCH v3] isdn: divamnt: use y2038-safe ktime_get_ts64() for
 trace data timestamps

> divamnt stores a start_time at module init and uses it to calculate
> elapsed time. The elapsed time, stored in secs and usecs, is part of
> the trace data the driver maintains for the DIVA Server ISDN cards.
> No change to the format of that time data is required.

> To avoid overflow on 32-bit systems use ktime_get_ts64() to return

> This is a change from real to monotonic time. Since the driver only
> stores elapsed time, monotonic time is sufficient and more robust
> against real time clock changes. These new monotonic values can be
> more useful for debugging because they can be easily compared to
> other monotonic timestamps.

> Note elaspsed time values will now start at system boot time rather

> Remove declaration and init of previously unused time constants:
