Mechnism for sharing data between kernel and user space

[jitendra kumar khasdev]

Hi All,

I am exploring the mechanism for sharing data between kernel and user
space. There are following mechanism I have found

   1. copy_to_user/copy_from_user
   2. Netlink sock
   3. /proc, /debugfs etc.

Other than this, Is there any efficient way of which I could read/write
linked-list that I have created from my kernel module.
