+Subject: gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag
+
+From: Andreas Gruenbacher <agruenba@redhat.com>
+
+commit 7c9d9223802fbed4dee1ae301661bf346964c9d2 upstream.
+
+Truncate an inode's address space when flipping the GFS2_DIF_JDATA flag:
+depending on that flag, the pages in the address space will either use
+buffer heads or iomap_folio_state structs, and we cannot mix the two.
