No, rename is guaranteed to be atomic by the OS. It's commonly used for
synchronization. Therefore, ideally the filesystem should implement it
atomically as well. JFFS did it atomically because of this, to avoid
surprises should the system crash during the operation.
(usual disclaimers about rename and NFS or between filesystems apply)
