Subject: [PATCH 02/10] afs: Don't use certain internal folio_*() functions

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/afs/*.c
perl -p -i -e 's/folio_file_mapping[(]([^)]*)[)]/\1->mapping/g' fs/afs/*.c
perl -p -i -e 's/folio_index[(]([^)]*)[)]/\1->index/g' fs/afs/*.c
