PAGE_MAPPING_DAX_SHARED is the same as PAGE_MAPPING_ANON. This isn't
currently a problem because FS DAX pages are treated
specially. However a future change will make FS DAX pages more like
normal pages, so folio_test_anon() must not return true for a FS DAX
page.

Yes, very nice to see PAGE_MAPPING_DAX_SHARED go!
