- Add comment to PageCompound() check. I didn't create a helper for it
  because it's not clear what function to wrap. It could be
  find_or_create_page(), find_lock_page(), or any other way we could get
  a page cache page. So, if we end up needing it anywhere else, we can
  create a common helper. For now, I think it's better to have an
  explicit check rather than obscure it behind a one-off helper.

Ok, the comment is sufficient for now. Added to misc-next, thanks.
