From eb050d976ccdff8c5499a826c19a818868824393 Mon Sep 17 00:00:00 2001 From: Shawn Landden Date: Sun, 24 Nov 2013 22:36:28 -0800 Subject: net: update consumers of MSG_MORE to recognize MSG_SENDPAGE_NOTLAST commit d3f7d56a7a4671d395e8af87071068a195257bf6 upstream. Commit 35f9c09fe (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag MSG_SENDPAGE_NOTLAST, similar to MSG_MORE. algif_hash, algif_skcipher, and udp used MSG_MORE from tcp_sendpages() and need to see the new flag as identical to MSG_MORE. This fixes sendfile() on AF_ALG. v3: also fix udp Cc: Tom Herbert Cc: Eric Dumazet Cc: David S.
