Subject: [PATCH net-next v3 18/18] net: Kill MSG_SENDPAGE_NOTLAST
Date: Tue, 20 Jun 2023 15:53:37 +0100 [thread overview]
Message-ID: <20230620145338.1300897-19-dhowells@redhat.com> (raw)
In-Reply-To: <20230620145338.1300897-1-dhowells@redhat.com>
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.
