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
