Hm I wonder if we could just ideally have this be a separate flag rather than a
bitwise combination, however I bet there's code that does somehow rely on this.
Well, KSM folios are anon folios, so that must hold.
Of course, now you could make folio_test_anon() test both bits, and have
KSM folios only set a PAGE_MAPPING_KSM bit.
That should be possible on top of this change, but not sure if that's
really what we want. After all, KSM folios are special ANON folios.
I know for sure there's code that has to do a folio_test_ksm() on something
folio_test_anon()'d because the latter isn't sufficient.

Yes :)
Nice: re change to folio, that is a nice cleanup based on fact you've now made
the per-page mapping op stuff not be part of this.
