    Correctly update fs_dsize in growfs(8)
    
    When growing a UFS/FFS filesystem, the size of the summary information
    may expand into additional blocks. These blocks must be removed from
    fs_dsize which records the number of blocks in the filesystem that can
    be used to hold filesystem data.
    
    While here also update the fs_old_dsize and fs_old_size fields for
    compatibility with kernels that were compiled before the addition
    of UFS2.

Unfortunately, testing this looks like it would be going back
through your sequence/usage pattern that lead to the problem,
to see if it is avoided. It is not a way to fix an existing
UFS2/FFS problem.
