For things that are file backed you DO NOT need to dump them. (sorry typo). > Are we talking about the VMA itself, or the memory backing the VMA? The memory backing the VMA. We need to store the page protections that the memory was mapped with as well now that you point it out. A VMA is not user space visible, which is why we can arbitrarily split and merge VMAs.
