It's a straight-forward conversion except that readahead_folio() will do folio_put() in advance but it doesn't matter since folios are still locked. As before, since file-backed folios (pages for now) are locked, so we could temporarily use folio->private as an internal counter to indicate split parts of each folio for the corresponding pclusters to decompress. When such counter becomes zero, the folio will be finally unlocked (see compress.h and z_erofs_onlinepage_endio()).
