Nit picking: making a hard link to a file creates a directory entry and
increments the link count in the inode so the overhead is a directory
entry. Another way to think of this is that a file is defined by its
inode and it has zero or more names: each name is a directory entry that
maps the name to the inode number and the number of names is link count
in the inode. I can't imagine that AIX would be any different to any
other Unix in this regard.
