I don't know much about NFS though, I imaged the NFS just fill the
stat.st_nlink to return to userland by 0 if sillyrenamed dentry? (of
course, I'm not saying let's emulate "i_nlink >= 1" on all
filesystems. just about i_nlink == 0) I was thinking Al is working for
it...

And yeah, if it doesn't have consistency on system, I would agree it
would not be meaningful.

Thanks.
