I think it needs a much bigger change i.e need to move the framework to kernel space to control this from user space.

In short, I need to get this done in kernel as I want this module to fit in the current framework. Please suggest if you have any implementation specific idea for this.

Thanks,

Sid

Why aren't you controlling that from userspace as well?
