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.

Yes, I was thinking at this callback too. Such a callback is
nearly the only support we need from the filesystem to provide
allocate on flush.
I think a callback is the way to go.
