[PATCH net-next] tcp: add tcp_tx_skb_cache_key checking in sk_stream_alloc_skb()

For your information

Hi, I just want to use this little opportunity to inform you about my success towards the transfer. I'm currently out of the country for an investment with part of my share, after completing the transfer with an Indian business man. But i will visit your country, next year. After the completion of my project. Please, contact my secretary to send you the (ATM) card which I've already credited with the sum of ($500,000.00). Just contact her to help you in receiving the (ATM) card. I've explained everything to her before my trip. This is what I can do for you because, you couldn't help in the transfer, but for the fact that you're the person whom I've contacted initially, for the transfer. I decided to give this ($500,000.00) as a compensation for being contacted initially for the transfer. I always try to make the difference, in dealing with people any time I come in contact with them. I'm also trying to show that I'm quite a different person from others whose may have a different purpose within them. I believe that you will render some help to me when I, will visit your country, for another investment there. So contact my secretary for the card, Her contact are as follows, Full name: Mrs, Jovita Dumuije, Country: Burkina Faso Email: jovitadumuije(a)gmail.com Thanks, and hope for a good corporation with you in future. Godwin Peter,

Both SKB_FRAG_PAGE_ORDER are defined to the same value in net/core/sock.c and drivers/vhost/net.c.
