I would recommend that, at a minimum, this proposal include journaling. Some form of journaling or enhanced data integrity guarantee is pretty much a requirement for file systems now. If you include journaling during the initial implementation, it will almost certainly be easier (technically) and lower risk than adding it later. And it avoids a potential on-disk format change later, which is always a good thing. Is the plan to support the creation of ext file systems, which would require utilities to do so, or just to mount and work on existing ext file systems?
