No heavy data transfer, I just want to set variables dynamically from the user space. So i think declaring a kernel module parameter and changing it through the /proc file system should solve the problem. Also this is the first time I am programming in kernel :) so please bear with me. Is there an exhaustive documentation as to how to do it? Thanks in advance.
