Guangguan Wang 7b42621ce5 net/smc: non blocking recvmsg() return -EAGAIN when no data and signal_pending ... [ Upstream commit f3c46e41b3 ] Non blocking sendmsg will return -EAGAIN when any signal pending and no send space left, while non blocking recvmsg return -EINTR when signal pending and no data received. This may makes confused. As TCP returns -EAGAIN in the conditions described above. Align the behavior of smc with TCP.
