Yech, nfs uses d_splice_alias(), so we'd have to add some logic to
throw away any preloaded entries there if we actually have an alias
and end up merging and using the alias. Or something. Because I think
we'd have a dentry leak otherwise.
So it wouldn't work "as-is", but it might still be reasonably easy.
