I guess what we wanted is a patch that addresses the concern of both patches and not a combination of the patches. IMHO the dirty notification of David's patch is possible with the shared dirty pages patch if we allow the set_page_dirty method in address operations to sleep and return an error code. However, this may raise some additional issues because we have to check whenever we dirty a page.
