It is not possible to do with a simple rename() operation, which mv uses.

I suppose their mv's do a copy-and-delete to simulate the operation.
The GNU mv used by most Linux systems does not seem to do that for
directories (I'm counting on your word on this), although it does it for
files. IMHO, it should be considered a bug.

Anyway, this is not a kernel issue.
