Eric Dumazet 1d2077ac01 net: add __sock_wfree() helper ... Hosts sending lot of ACK packets exhibit high sock_wfree() cost because of cache line miss to test SOCK_USE_WRITE_QUEUE We could move this flag close to sk_wmem_alloc but it is better to perform the atomic_sub_and_test() on a clean cache line, as it avoid one extra bus transaction. skb_orphan_partial() can also have a fast track for packets that either are TCP acks, or already went through another skb_orphan_partial() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
