* Return a CPU-local timestamp in nano-seconds. This timestamp is
* NOT synchronized across CPUs its return value must never be
* compared against the values returned on another CPU. The usage in
- * kernel/sched.c ensures that.
+ * kernel/sched/core.c ensures that.
*
* The return-value of sched_clock() is NOT supposed to wrap-around.
* If it did, it would cause some scheduling hiccups (at the worst).
