case.c

I have encountered a bug in F2FS file system in kernel v5.17.

The file operations performed on the file system are in case.c, and I have
uploaded the F2FS image to the google net disk
(https://drive.google.com/file/d/1SQ5oHSMJLD_e_HtYRad6gcmVQU-dvLk3/view?usp=sharing).

The kernel should enable CONFIG_KASAN=y and CONFIG_KASAN_INLINE=y. 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:
