Thank you for adding documentation.  I have one additional
question regarding wrapping of sched_clock().  I know it is
used for timestamps in ftrace and printk, so it's desirable
that it never wraps.  But on several embedded systems
it wraps after a few hours.  Bug or just a minor flaw?
If someone knows it would be nice to get that documented, too.
