Filesystems should not be using folio->index not folio_index(folio) and
folio->mapping, not folio_mapping() or folio_file_mapping() in filesystem
code.
Change this automagically with:
perl -p -i -e 's/folio_mapping[(]([^)]*)[)]/\1->mapping/g' fs/erofs/*.c
perl -p -i -e 's/folio_file_mapping[(]([^)]*)[)]/\1->mapping/g' fs/erofs/*.c
perl -p -i -e 's/folio_index[(]([^)]*)[)]/\1->index/g' fs/erofs/*.c
