Ref: InfiniFS: An Efficient Metadata Service for Large-Scale Distributed Filesystems.

In figure 8, when two clients concurrently rename paths with longer hierarchies, an orphaned loop may be created.

It's a rare case, but is it possible to happen in JuiceFS? e.g. in tikv, I suppose those two rename ops won't even conflict?
