5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Andreas Gruenbacher <agruenba@xxxxxxxxxx> 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.
