4.3-stable review patch. If anyone has any objections, please let me know. ------------------ From: "tadeusz.struk@xxxxxxxxx" <tadeusz.struk@xxxxxxxxx> [ Upstream commit 130ed5d105dde141e7fe60d5440aa53e0a84f13b ] msg_iocb needs to be initialized on the recv/recvfrom path. Otherwise afalg will wrongly interpret it as an async call.
