That was really badly phrased. There can be _millions_ of these things, but they are all "unique" - they have zero impact on each other, and have no linkages. They never shadow any existing dentries (ie when we create these, we'd obviously never create a tentative dentry with the same name as an existing _valid_ dentry), and they are never visible to the filesystem.
So it's not that "only one dentry" exists, but that that this tentative dentry only exists as a unique marker of "a dentry of this name _may_ exist".
