It's called Journalling Flash File System (JFFS2) in its current incarnation.
David Woodhouse spoke about it at LCA 2002. I can't find a copy of his paper
from LCA, but the OLS version is linked off:
Its an interesting idea, but note that not all devices actually require
wear-leveling to be implemented in the filesystem. I'm not really across
which technologies implement wear leveling themselves, and which need
something like JFFS2. Perhaps someone else can clarify this bit.
