Karsten Graul ea438df46e net/smc: receive pending data after RCV_SHUTDOWN ... [ Upstream commit 107529e31a87acd475ff6a0f82745821b8f70fec ] smc_rx_recvmsg() first checks if data is available, and then if RCV_SHUTDOWN is set. There is a race when smc_cdc_msg_recv_action() runs in between these 2 checks, receives data and sets RCV_SHUTDOWN. In that case smc_rx_recvmsg() would return from receive without to process the available data. Fix that with a final check for data available if RCV_SHUTDOWN is set. Move the check for data into a function and call it twice. And use the existing helper smc_rx_data_available().
