This small cacheline adjustment of struct netns_frags improves performance significantly for the fragmentation code. Struct members 'lru_list' and 'mem' are both hot elements, and it hurts performance, due to cacheline bouncing at every call point, when they share a cacheline. Also notice, how mem is placed together with 'high_thresh' and 'low_thresh', as they are used in the compare operations together.
