Why? What problem are you trying to solve by doing this? This is almost certainly a bad design, for a number of reasons. And there's probably a better way to do what you're trying to accomplish.

I read about using filp_open , will this help me ?

Probably not.

I guess you want to open the files inside kernel and then copy from one to another. That's just not good. If you are trying to learn something like passing data from user space to kernel, you should probably look at sysfs. Very simple wrappers exist that allow you to create a dummy sysfs file(s) where you can have your store and show callbacks do the magic you want to learn.

Thanks, Nada
