Well the structure is going to be 12 bytes wide. Since pointers have to be aligned to 8 bytes we will effectively have to use 16 bytes anyways. There is no additional memory use if we would be adding another 4 bytes.
But lets get this merged. We can sort this out later. Too many oscillations already. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
