Yup, that is correct. I got the VMA all set up through a file op foo_mmap(), so all is correctly mapped. What I need is indeed a way to translate a kernel logical address to its mapped user virtual address. Ps. Sorry for the extra email to you yogeshwar sonawane, I pressed the narrow reply key first.
