z3fold doesn't really use folios, but it needs to be called like this
in order to migrate an individual page. Convert from a folio back to

There is nothing iomap-specific about iomap_migratepage(), and it fits
a pattern used by several other filesystems, so move it to mm/migrate.c,
convert it to be filemap_migrate_folio() and convert the iomap filesystems
to use it.

Switch f2fs over to the functions that are replacing
fscrypt_set_test_dummy_encryption(). Since f2fs hasn't been converted
to the new mount API yet, this doesn't really provide a benefit for
