fsck_ufs cleanup phase

After a filesystem has been checked, a few cleanup functions are performed. The cleanup phase displays advisory messages about the status of the filesystem:

V files, W used, X free (Y frags, Z blocks)

This is an advisory message indicating that the filesystem checked contains V files using W fragment-sized blocks, and that there are X fragment sized blocks free in the filesystem. The numbers in parentheses break the free count down into Y free fragments and Z free full sized blocks.

***** FILE SYSTEM WAS MODIFIED *****

This is an advisory message indicating that the filesystem was modified by fsck. If this filesystem is mounted or is the current root filesystem, you should reboot the system. If the filesystem is mounted you might need to unmount it and run fsck again; otherwise the work done by fsck might be undone by the in-core copies of tables.
