This is only true only *after* Jan's patches are applied, right?  So
that means it's only safe to apply this after Jan's patch series is
applied.  So I believe I need to queue this in the unstable portion of
the patch queue until the page_mkwrite() changes are applied;
otherwise we could have some spurious WARN_ON's.
