Hi Jeff,
Thanks for your help, finally I found this in kernel document.
Pointer Types
=
Pointers printed without a specifier extension (i.e unadorned %p) are hashed to
give a unique identifier without leaking kernel addresses to user space. On 64
bit machines the first 32 bits are
Hi,
To print kernel virtual address, you should use %px instead of %p in the printk.
Probably that’s why you couldn’t see the pointer values correctly.

Think about this carefully. When you insmod that kernel module which
address space is it using ? Kernel or Userspace ? :-)
This will help:

Hi,
I'm developing a kernel module for an ARM machine, while debugging I found
addresses
printed are all randomized and useless for debugging.
To prove I was not crazy I wrote this small program:
