The ktime_get() can have a non negligeable overhead, use local_clock()
instead.
In order to test the difference between ktime_get() and local_clock(),
a quick hack has been added to trigger, via debugfs, 1 times a
call to ktime_get() and local_clock() and measure the elapsed time.
Then the
The ktime_get() can have a non negligeable overhead, use local_clock()
