As for the application, this work looks fairly similar to this USENIX paper from an Alibaba team:

The above paper describes a virtual block device, implemented in user space, and including crash recovery. The overall application is to deliver block-based container images to their platform.

As the same Alibaba team member, I can tell it's not used for this scenario but for distributed block device.
Instead, for container image scenarios, we will try to write a new paper based on the filesystem approach, hopefully later published.

Thanks for the update! For what it's worth, the existing paper was quite fun to read...

Hi. I am Ziyang Zhang. This patchset has nothing to do with DADI. I developed it by myself.

By the way, ublk is not for container images. It is a generic userspace block driver. Please read related articles published before more patiently, really.
