This is in preparation for the removal of find_get_pgaes_range_tag(). This change removes 8 calls to compound_head(). Also had to modify and rename gfs2_write_jdata_pagevec() to take in and utilize folio_batch rather than pagevec and use folios rather than pages. gfs2_write_jdata_batch() now supports large folios.
