Move small files? What for?

WAFL-style filesystems like contiguous space, so if small files are
scattered in otherwise free space, the repacker should free them.
Even if it is "only" moving metadata, it is not different from what ext3
or xfs are doing today (rewriting metadata from the intent log or block
journal to the final location).

There is no need to repack all metadata; only that which helps in
creating free space.
For example: if you untar a source tree you'd get mixed metadata and
small file data packed together, but there's no need to repack that data.
