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)
