Eric Dumazet e370a72363 af_unix: improve STREAM behavior with fragmented memory ... unix_stream_sendmsg() currently uses order-2 allocations, and we had numerous reports this can fail. The __GFP_REPEAT flag present in sock_alloc_send_pskb() is not helping. This patch extends the work done in commit eb6a24816b ("af_unix: reduce high order page allocations) for datagram sockets. This opens the possibility of zero copy IO (splice() and friends) The trick is to not use skb_pull() anymore in recvmsg() path, and instead add a @consumed field in UNIXCB() to track amount of already read payload in the skb. There is a performance regression for large sends because of extra page allocations that will be addressed in a follow-up patch, allowing sock_alloc_send_pskb() to attempt high order page allocations.
