Well, it might decide it would be nicer if some elements were aligned to 64 bits. Or to a cache line. Or something. I don't care about _why_ -- the point is that it's _allowed_ to. Hence the original use of __attribute__((packed)). In practice, there's no real reason why it would do such a thing, which is why I removed the packed attribute and replaced it with a runtime check on the size of the structures in question. -- dwmw2 - 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/
