  "message": "net: more accurate skb truesize\n\nskb truesize currently accounts for sk_buff struct and part of skb head.\nkmalloc() roundings are also ignored.\n\nConsidering that skb_shared_info is larger than sk_buff, its time to\ntake it into account for better memory accounting.\n\nThis patch introduces SKB_TRUESIZE(X) macro to centralize various\nassumptions into a single place.\n\nAt skb alloc phase, we put skb_shared_info struct at the exact end of\nskb head, to allow a better use of memory (lowering number of\nreallocations), since kmalloc() gives us power-of-two memory blocks.\n\nUnless SLUB/SLUB debug is active, both skb-\u003ehead and skb_shared_info are\naligned to cache lines, as before.\n\nNote: This patch might trigger performance regressions because of\nmisconfigured protocol stacks, hitting per socket or global memory\nlimits that were previously not reached. But its a necessary step for a\nmore accurate memory accounting.\n\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCC: Andi Kleen \u003cak@linux.intel.com\u003e\nCC: Ben Hutchings \u003cbhutchings@solarflare.com\u003e\nSigned-off-by: David S.
