There would not seem to be any _need_ to do so. An unnecessary null test is always safe. The only real problem that I can see with an unnecessary null test in error handling code (intrinsically not critical performance wise) is if it gives the illusion that a value can be null when it cannot. julia -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
