I have mounted a Ext4 image with several mount options. When I try to create a file on the mount point, the kernel hangs. The process even cannot be killed. I am wondering whether there is a bug in the file system?

This issue can be reproduced by running the following commands:
losetup /dev/loop0 case.img
mount -o "acl,oldalloc,user_xattr,jqfmt=vfsv1,nojournal_checksum,nobarrier,inode_readahead_blks=8,journal_ioprio=7,auto_da_alloc,init_itable=0,noblock_validity,dioread_lock,minixdf,errors=remount-ro" /dev/loop0 /mnt/test/
touch /mnt/test/test
