That patch was an abortion. Adding a config option for behavior like
this is totally bogus, and the only reason for that config option was
that sysfs did silly things.

It's only in -next, though, I was assuming that the whole "Kill nlink
counting" commit never makes it to me. Because I won't take it.

I outlined how the counting could easily be done without actually
having to maintain an explicit count in the sysfs.

Or we should just keep doing the counting.
