Miller <davem@davemloft.net> 2017-06-16networking: make skb_put & friends return void pointersJohannes Berg It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

Miller <davem@davemloft.net> 2017-02-18target/cxgbit: add T6 iSCSI DDP completion featureVarun Prakash Chelsio T6 adapters reduce number of completion to host by generating single completion for all directly placed(DDP) iSCSI pdus in a sequence, completion contains iSCSI hdr of the last pdu in a sequence. On receiving DDP completion cxgbit driver finds iSCSI cmd using iscsit_find_cmd_from_itt_or_dump(), then updates cmd->write_data_done, cmd->next_burst_len, cmd->data_sn and calls __iscsit_check_dataout_hdr() to validate iSCSI hdr.
