Speaking of the LongFile Name patent and Journaling, there was if I
recall, a Linux kernel hacker a while back that addressed both with an
interesting patch. If I recall correctly, rather than storing a LFN
and a SFN it would only store one or the other and then use the other
record as some sort of a checksum on the file in question to achieve a
similar effect as a journal record. Maybe its more analogous to UFS
soft updates but I think you might get the idea. I'm not all that up
on filesystem semantics but I think a bit of googling might turn up
what I am talking about.
