I created a disk image and modified some properties. After that, I mount the image and run some commands related to file operations, and the bug occurs. The file operations are in the "case.c" file, and a modified image named "case.img" can be achieved from (https://drive.google.com/file/d/1--eGC9FZW4aXt35kjpKwUp5k6k1qIpcx/view?usp=sharing). You can reproduce the bug by running the following commands: gcc -o case case.c losetup /dev/loop0 case.img mount -o "background_gc=sync,disable_roll_forward,nouser_xattr,disable_ext_identify,nobarrier,fastboot,mode=adaptive,grpquota,noquota,alloc_mode=reuse,test_dummy_encryption" -t f2fs /dev/loop0 /root/mnt ./case The kernel message is shown below: 6,799,86253155,-;loop0: detected capacity change from 0 to 262144 4,800,86288111,-;F2FS-fs (loop0): Test dummy encryption mount option ignored 5,801,86289902,-;F2FS-fs (loop0): Disable nat_bits due to incorrect cp_ver (7347879550090329573, 6600135115475369443) 5,802,86315906,-;F2FS-fs (loop0): Mounted with checkpoint version = 237dbde5 4,803,86343451,-;F2FS-fs (loop0): access invalid blkaddr:4293918720 4,804,86343471,-;------------[ cut here ]------------ 4,805,86343473,-;WARNING: CPU: 2 PID: 1047 at fs/f2fs/checkpoint.c:192 f2fs_is_valid_blkaddr+0xbf5/0xe50 4,806,86343480,-;Modules linked in: x86_pkg_temp_thermal efivarfs 4,807,86343486,-;CPU: 2 PID: 1047 Comm: case Not tainted 5.17.0 #2 4,808,86343489,-;Hardware name: Dell Inc.
