Subject: [PATCH] RDS: TCP: start multipath acceptor loop at 0
The for() loop in rds_tcp_accept_one() assumes that the 0'th
rds_tcp_conn_path is UP and starts multipath accepts at index 1.
But this assumption may not always be true: if the 0'th path
has failed (ERROR or DOWN state) an incoming connection request
should be used to resurrect this path.
