I know, but creating a new dir entry and linking to an existing dir entry
is not always the same, e.g. filesystems, where a dir entry is not simply
a pointer to an inode table, have to update other entries as well to
create a new link. So far filesystems could assume that source dentry was
a valid dir entry, this patch changes this.
