In absence of extension headers, message log will keep flooding the console. As such even without use_once we can clean up the MRs so its not really an error case message so make it debug message Signed-off-by: Santosh Shilimkar --- net/rds/rdma.c | 3 ++- 1 file changed, 2 insertions(+), 1

[net-next][PATCH 17/18] RDS: add receive message trace used by application

Socket option to tap receive path latency in various stages in nano seconds. It can be enabled on selective sockets using using SO_RDS_MSG_RXPATH_LATENCY socket option. RDS will return the data to application with RDS_CMSG_RXPATH_LATENCY in defined format. Scope is left to add more trace points

Shutdown code reaping loop takes care of emptying the CQ's before they being destroyed. And once tasklets are killed, the hanlders are not expected to run. But because of core tasklet code issues, tasklet handler could still run even after tasklet_kill, RDS IB shutdown code already reaps the CQs

MR invalidation in RDS is done in background thread and not in data path like registration. So break the dependency between them which helps to remove the performance bottleneck. Signed-off-by: Santosh Shilimkar --- net/rds/ib.h | 4 +++- net/rds/ib_cm.c |

The first message to a remote node should prompt a new connection even if it is RDMA operation. For RDMA operation the MR mapping can fail because connections is not yet up. Since the connection establishment is asynchronous, we make sure the map failure because of unavailable connection reach to
