Yes，I will rename it to "fsck_vreport".

From my perspective, I think we should put the previous commit after
this commit. I agree with you that if we put it later, it will be
much clearer and eaiser to understand.

The original code's indentation breaks. There are one more space in each
line like the following:

  static int hash_format_check_report(struct fsck_options *opts UNUSED,
                                       const struct object_id *oid UNUSED)
                                       ...

I think I could fix this by the way.
