Dear list... If somehow I get a pointer to a page structure, how can I found out the process which owns it? Do I need to traverse all the page tables entry (not only the one related with current loaded Page Directory)? I have heard about reverse mapping but I am not sure is this the one I am looking for.... I will greatly appreciate if someone can also point me which kernel code provide such function....
