Date: Wed, 20 Sep 2017 13:58:05 +0200 From: Ursula Braun <ubraun@...ux.vnet.ibm.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, linux-rdma@...r.kernel.org, linux-s390@...r.kernel.org, jwi@...ux.vnet.ibm.com, schwidefsky@...ibm.com, heiko.carstens@...ibm.com, raspl@...ux.vnet.ibm.com, ubraun@...ux.vnet.ibm.com Subject: [PATCH net-next 02/10] net/smc: add receive timeout check From: Hans Wippel <hwippel@...ux.vnet.ibm.com> The SMC receive function currently lacks a timeout check under the condition that no data were received and no data are available. This patch adds such a check.
