I think that you may be referring to the fact that on Windows any open operation
takes out a "path lock" on every dereferenced name along the path to the target
file.  This semantic is an underpinning of SMB/CIFS.  That is in SMB/CIFS the
abstraction of a file system has no conceptual equivalent to inode numbers / file
indices.  Thus, using only the concepts available within the abstraction, the
only way to convey the identity of an open file is by its path.
