Sure, there's an extra SMAP sequence for people using longer names, but while those SMAP things are costly compared to individual instructions, they aren't costly in the *big* picture. They are a pipeline stall, not some kind of horrendous thing. It would be *more* expensive to try to keep statistics than it is to just say "long pathnames are more expensive than short ones". Linus
