XIP filesystems can now be tested quite easily using the new rd driver (brd). There is a config option which allows this to support direct access by XIP filesystems. It might be possible to patch brd to allocate memory early with no struct pages somehow, or even put poison into the struct page and ensure it hasn't been touched... however I think it would be most useful just to start testing XIP. Using brd and ext2, try running your regular vm/vfs/filesystem tests against that. You'll probably find some tests will fail by design, but we can go through and weed those out.
