It looks the original code didn't return -ENOENT either, I'm not sure if this is a document issue or not. Anyway this is another issue, once we confirm it we can fix it later.

No, I think it is important to figure out this in the first place. Otherwise, it is pointless to touch this piece of code over and over again, i.e., this is not another issue but the core of this problem on hand.
