Commit 35f9c09fe (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag MSG_SENDPAGE_NOTLAST, similar to MSG_MORE. algif_hash and algif_skcipher used MSG_MORE from tcp_sendpages() and need to see the new flag as identical to MSG_MORE. This fixes sendfile() on AF_ALG. Cc: Tom Herbert <therbert@xxxxxxxxxx> Cc: Eric Dumazet <eric.dumazet@xxxxxxxxx> Cc: David S.
