BTW, if you look at the function above this one (memcpy_toiovecend) it avoids this issue by encompassing all of the logic in a top-level loop which terminates when len <= 0. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
