It is quite grotesque!

How about folio_track_foreign_writeback() as a replacement name for
mem_cgroup_track_foreign_dirty() and have it call
__folio_track_foreign_writeback()?

Although 'foreign' tends to be used in MM to mean "wrong NUMA node",
so maybe that's misleading.  folio_track_dirty_cgroup()?
folio_mark_dirty_cgroup()?  (the last to be read in context of
__set_page_dirty() being renamed to __folio_mark_dirty())
