Yes, we need to add one field to the in-core superblock to do this accounting.
How does this work for filesystems like reisefs which do tail merging and other filesystems which might do sub-clock allocation?
We either need more than one field (or a byte counter) + lock or perhaps a generic fields + callback to the fs itself.

I think a callback is the way to go.
