case.c, contains file operations
I'd mounted a F2FS image with several mount options. When I was performing file
operations on the mount point, the kernel hangs, and the process cannot be
killed.
The file operations are in case.c, and the image is provided at
(https://drive.google.com/file/d/1be1SyKJwBWvQKSnhD0Y05ZquEIPT62-W/view?usp=sharing).
This issue can be reproduced by running the following commands:
losetup /dev/loop0 case.img
mount -o
"background_gc=sync,active_logs=4,disable_ext_identify,inline_dentry,data_flush,fsync_mode=posix"
/dev/loop0 /mnt/test/
gcc -o case case.c
./case
