hi all:
       As far as I known, the var jiffies in the kernel will overflow after
497days as the Hz defined 100. So what waill happen when the jiffies
overflow?
It will start back at zero.

Everything should continue to work as before.

In fact, jiffies are initialized to -300 seconds, so that it will
overflow 5 minutes after startup, just to verify that everything works
properly.
