Date: Mon, 24 Nov 2014 13:32:16 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: "David S. Miller" <davem@...emloft.net>, Daniel Borkmann <dborkman@...hat.com>, Eric Dumazet <edumazet@...gle.com>, Atzm Watanabe <atzm@...atosphere.co.jp>, Hannes Frederic Sowa <hannes@...essinduktion.org>, Tom Herbert <therbert@...gle.com>, netdev@...r.kernel.org Subject: [PATCH] af_packet: fix sparse warning af_packet produces lots of these: net/packet/af_packet.c:384:39: warning: incorrect type in return expression (different modifiers) net/packet/af_packet.c:384:39: expected struct page [pure] * net/packet/af_packet.c:384:39: got struct page * this seems to be because sparse does not realize that _pure refers to function, not the returned pointer. Tweak code slightly to avoid the warning. Signed-off-by: Michael S.
