The objects around it are pointers, which are 64-bit, and thus the 32-bit object gets padded out to 64-bits in the layout of the struct so that the next pointer member can be properly aligned. It does not change the size of sk_buff at all. > Yes, it is a bug, but: > dev_hold/put dont work anymore? why do you need an ifindex instead? You sure you want to do that atomic operation on every single input packet, regardless of whether egresss operations are using it or not? We should put the cost of features at the actual users, and not impose it upon everyone. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
