Hi Folks, I am sure there is a reason for the current sizes of these structures, However the reason is not obvious to me. So please help me understand.
Currently the size of sk_buff on an x86_64 system is 232 bytes -- Why is that. I expected it to be a multiple of 32/64 as they are the most common cache lines. Since the alignment calculation will align the structure with the hw cache line, it seems like we might be wasting space ? skb_shared_info on the other hand is perfectly aligned with a size of 320 bytes. Thanks, -- CS1
