Once you start adding more "case folding" supported filesystems to the repertoire, such a unified hash function Dscho suggests needs to throw paths that other (N-1) "case folding" filesystems treat as distinct but only 1 filesystem treats "equivalent" into the same hash bucket. I would say not just difficult but the resulting function would have too many collisions to make it ineffective. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
