I have mounted a Ext4 image with several mount options. When I try to creat=
e a
file on the mount point, the kernel hangs. The process even cannot be kille=
d. 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=3Dvfsv1,nojournal_checksum,nobarrier,inode_r=
eadahead_blks=3D8,journal_ioprio=3D7,auto_da_alloc,init_itable=3D0,noblock_=
validity,dioread_lock,minixdf,errors=3Dremount-ro"
/dev/loop0 /mnt/test/
touch /mnt/test/test
