[RFC PATCH v2 0/2] vsock: handle writes to shutdowned socket
...ocket which was shutdowned with 'shutdown()' (both sides - local with
>SHUT_WR flag, peer - with SHUT_RD flag). According POSIX we must send
>SIGPIPE in such cases (but SIGPIPE is not send when MSG_NOSIGNAL is set).
>
>First patch is implemented in the same way as net/ipv4/tcp.c:tcp_sendmsg_locked().
>It uses 'sk_stream_error()' function which handles EPIPE error. Another
>way is to use code from net/unix/af_unix.c:unix_stream_sendmsg() where
>same logic from 'sk_stream_error()' is implemented "from scratch", but
>it doesn't check 'sk_err' fi...

[PATCH net-next v2 17/17] net: Kill MSG_SENDPAGE_NOTLAST
Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned
up. Things were converted to use MSG_MORE instead, but the protocol
sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now
unnecessary.
