There's actually one hell of a stronger reason for that particular change; uses of ->d_name in ->d_revalidate() instances are often racy. So IMO this is the right way to go, regardless of c-i stuff, except that it ought to be followed by making individual ->d_revalidate() instances use the damn argument, now that they have it in stable form. Said followups don't need to be in the same series, obviously.
