[PATCH net-next v2 16/17] sock: Remove ->sendpage*() in favour of sendmsg(MSG_SPLICE_PAGES)

Remove ->sendpage() and ->sendpage_locked(). sendmsg() with MSG_SPLICE_PAGES should be used instead. This allows multiple pages and multipage folios to be passed through. Signed-off-by: David Howells Acked-by: Marc Kleine-Budde # for net/can cc: "David S. Miller" cc: Eric Dumazet cc: Jakub

[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. Signed-off-by: David Howells cc: "David S. Miller" cc: Eric
