What are you trying to accomplish here? And why isn't using mlock() from the userspace program an option? Also, remember that a vma can change in size. If it increases, something will need to lock the newly added pages. (There's a good chance that locking the pages isn't really what you wanted, and there's some other way to achieve whatever goal you're chasing here)
