i use the __init for function print_k.
in my opinion  after the fisrt invoking the print_k in the hello_init.
the memory of print_k will be freed,and the second invoking will
not be executed.but the result of second invoking is executing .

why?
because you're still in module_init.... :)
Yes, and the function is still in the stack!

On the other hand.. think what would happen if things would work
like you say.

We would have a *very* strange behavior,
and pretty counter-intuitive, don't you think so?
   Thank you very much  for reply.
   as you say,and function is still in the stack,don't be freed
   in the memory,what is __init had done? who can give a sample example
  to explain the difference existing __init or not?
