We can now simply check for PageAnon() and remove PageMappingFlags().

... and while at it, use the folio instead and operate on
folio->mapping.

Probably worth mentioning to be super crystal clear that this is because
now it's either an anon folio or a KSM folio, both of which set the
FOLIO_MAPPING_ANON flag.

"As PageMappingFlags() now only indicates anon (incl. ksm) folios, we 
can now simply check for PageAnon() and remove PageMappingFlags()."

I wonder if there's other places that could be fixed up similarly that do
folio_test_anon() || folio_test_ksm() or equivalent?

I think you spotted the one in patch #25 :)

I looked for others while crafting this patch, but there might be more 
hiding that I didn't catch.
