Created attachment 300824 [details] case.c I have mounted a F2FS image on the Linux system. When I was performing file operations on the mounted directory, the kernel hangs. I tried to kill the running process but failed. Any operations on the directory have no response. I am wondering whether a deadlock is in the kernel. This issue can be reproduced by running the following scripts: gcc -o case case.c losetup /dev/loop0 case.img mount -o "disable_ext_identify,inline_data,nobarrier,extent_cache,grpquota,fsync_mode=nobarrier,test_dummy_encryption" -t f2fs /dev/loop0 /root/mnt ./case The image can be found at (https://drive.google.com/file/d/1bjCQR_-Sz6iF_wshMGU3wWZDQ8tQIFdj/view?usp=sharing)
