There's no need to give the page an address_space. Leaving the page->mapping as NULL will cause the VM to handle set_page_dirty() the same way that it's handled now, and that was the only reason to set the address_space in the first place.

This patch in mainline as commit ccf953d8f3d6 ("fb_defio: Remove custom address_space_operations") causes my Hyper-V based VM to no longer make it to a graphical environment.
Hi Nathan,
Thanks for the report. I sent Daniel a revert patch with a full explanation last week, which I assume he'll queue up for a pull soon. You can just git revert ccf953d8f3d6 for yourself until that shows up. Sorry for the inconvenience.
