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? -------------- next part -------------- An HTML attachment was scrubbed...
