From 7c9d9223802fbed4dee1ae301661bf346964c9d2 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Mon, 13 Jan 2025 19:31:28 +0100 Subject: [PATCH] gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag 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.
