Now that the splice_to_socket() has been rewritten so that nothing now uses
the ->sendpage() file op[1], some further changes can be made, so here are
some miscellaneous changes that can now be done.
(1) Remove the ->sendpage() file op.
(2) Remove hash_sendpage*() from AF_ALG.
(3) Make sunrpc send multiple pages in single sendmsg() call rather than
calling sendpage() in TCP (or maybe TLS).
(4) Make tcp_bpf_sendpage() a wrapper around tcp_bpf_sendmsg().
(5) Make AF_KCM use sendmsg() when calling down to TCP and then make it
send entire fragment lists in single sendmsg calls.
I've pushed the patches here also:
