There is no _locked_ chain. And if you want to grab the locks on all
ancestors - think again. It means sorting the inodes by address _and_
relocking if any of them had been moved while you were locking the
previous ones. I absolutely refuse to add such crap to the tree and I
seriously suspect that Linus and Alan will do the same.
