Date: Tue, 12 Oct 2010 07:15:50 +0200 From: Gerrit Renker <gerrit@....abdn.ac.uk> To: davem@...emloft.net Cc: dccp@...r.kernel.org, netdev@...r.kernel.org, Gerrit Renker <gerrit@....abdn.ac.uk> Subject: [PATCH 5/6] dccp: schedule an Ack when receiving timestamps This schedules an Ack when receiving a timestamp, exploiting the existing inet_csk_schedule_ack() function, saving one case in the `dccp_ack_pending()' function.
