Well, I think I need to dive into the "open" system call here. Actually,
we have two opinions now. Junio thought that we should use
"fsck_report_ref" to report. Karthik, Patrick and I thought that we
should report using "*errno" because this is a general error.

Let me investigate what situations will make "open" system call fail.
Thus, we could fully explain which choice we will choose.
