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,

[PATCH net-next] sock: remove one redundant SKB_FRAG_PAGE_ORDER macro

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

[PATCH net-next 000/143] net: extend the netdev_features_t
by Jian Shen 18 Aug '21

18 Aug '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to bitmap. With this change, it's neccessary to introduce a set of bitmap operation helpers for netdev features. Meanwhile, the functions which use netdev_features_t as return value are also need to be changed, return the result as an output parameter. With above changes, it will affect hundreds of files, and all the nic drivers. To make it easy to be reviewed, split the changes to 124 patches to 6 parts. patch 1: code optimization for hns3 driver patch 2~23: convert the prototype which use netdev_features_t as return value patch 24: introduce fake helpers for bitmap operation patch 25~141: use netdev_feature_xxx helpers patch 142: use macro __DECLARE_NETDEV_FEATURE_MASK to replace netdev_feature_t declaration. patch 143: change the type of netdev_features_t to bitmap, and rewrite the bitmap helpers.
