            Bug ID: 215712
           Summary: kernel deadlocks while mounting the image
           Product: File System
           Version: 2.5
    Kernel Version: 5.15.4
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@...nel-bugs.osdl.org
          Reporter: yanming@....edu.cn
        Regression: No

I have created an image with mkfs.ext4, and modified some of the metadata of
the image. Unfortunately, when I tried to mount the image with a loop device,
the kernel deadlocked. I have attempted many ways to stop the mount process,
even executed a 'kill' command, but they are failed, only what I can do is to
reboot the system. Can anyone tell me why the kernel deadlocked, and how can I
fix this problem?

I have upload the image to the Google Drive
(https://drive.google.com/file/d/1NjUKdMufpoiyMscpFMdbiwOzyOios-aa/view?usp=sharing).
Looking forward to getting a reply :)
