From 76e18e6709c84af8cdc95e5c09437e29ec337d1c Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sat, 26 Aug 2023 17:28:48 +0200 Subject: [PATCH] Revert "f2fs: don't reset unchangable mount option in f2fs_remount()" This reverts commit e2fb24ce37caeaecff08af4e9967c8462624312b which is commit 458c15dfbce62c35fefd9ca637b20a051309c9f1 upstream. Something is currently broken in the f2fs code, Guenter has reported boot problems with it for a few releases now, so revert the most recent f2fs changes in the hope to get this back to a working filesystem.
