If the unlikely() hints are being used correctly and the compiler is doing the right thing then it ought to be worthwhile, if not then fix the compiler. Remember however unlikely() does have a code size cost on some processors and a small performance cost so it really has to mean very_unlikely(). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
