Sorry for being so very late to the party, but rather than messing

whiteout entries?
Don't the ext2 descendants have an array of reserved inodes at the
beginning (one of which is the journal for ext3, most of which were
still unused last I checked)?
Maybe ext4 optimized this away, but that would mean it doesn't have to
be anywhere in the namespace.
(Of course you'd have to teach fsck about it, and probably not update
the link count or you'll have contention and integer overflow...)
