The thing is, it really isn't really easy. As mentioned, it's actually
impossible on NFS, and it's possibly impossible on other filesystems
too.
So what I'm objecting to is "try to make something consistent that
CANNOT be consistent anyway", and calling it a bug.
I'm not saying there aren't real bugs there too (the actual races in
i_nlink handling are real bugs). But I _am_ saying that it's simply
not true that i_nlink must be zero if you do an "fstat()" after doing
an rmdir on an fd that you held open. Nobody can reasonably care, and
anybody who _does_ care is better off getting a nasty surprise early
rather than late.
