Nit: It would be nice, if you described here, what is the expected usage
of "ref_checkee" and "sub_ref_checkee".

This makes me really wonder if this is the best way we can do this? This
seems to solve for the current situation, but what happens if you want
to also adding the reftable size or packed-refs size here? Would you
introduce another field?
would it be better to add a single `const struct *fsck_refs_info`
instead?
Perhaps something like:
struct fsck_refs_info {
char *refname;
union {
struct {
...
} reftable;
struct {
...
} files;
} u;
}
Of course we can fill in the details as we need them.
