John Fastabend 29545f4977 bpf, sockmap: Remove skb_set_owner_w wmem will be taken later from sendpage ... The skb_set_owner_w is unnecessary here. The sendpage call will create a fresh skb and set the owner correctly from workqueue. Its also not entirely harmless because it consumes cycles, but also impacts resource accounting by increasing sk_wmem_alloc. This is charging the socket we are going to send to for the skb, but we will put it on the workqueue for some time before this happens so we are artifically inflating sk_wmem_alloc for this period. Further, we don't know how many skbs will be used to send the packet or how it will be broken up when sent over the new socket so charging it with one big sum is also not correct when the workqueue may break it up if facing memory pressure. Seeing we don't know how/when this is going to be sent drop the early accounting. A later patch will do proper accounting charged on receive socket for the case where skbs get enqueued on the workqueue.
