This patch series ensures that the passive (accept) side of the
TCP connection used for RDS-TCP is correctly synchronized with
any concurrent active (connect) attempts for a given pair of peers.
Patch 1 in the series makes sure that the t_sock in struct
rds_tcp_connection is only reset after any threads in rds_tcp_xmit
have completed (otherwise a null-ptr deref may be encountered).
Patch 2 synchronizes rds_tcp_accept_one() with the rds_tcp*connect()
path.
v2: review comments from Santosh Shilimkar, other spelling corrections
Sowmini Varadhan (2):
RDS:TCP: Synchronize rds_tcp_accept_one with rds_send_xmit when
resetting t_sock
RDS: TCP: Synchronize accept() and connect() paths on t_conn_lock.
