Merge branch 'for_4.11/net-next/rds_v3' of git://git.kernel.org/pub/scm/linux/kernel...

Santosh Shilimkar says:

====================
net: RDS updates

v2->v3:
- Re-based against latest net-next head.
- Dropped a user visible change after discussing with David Miller.
  It needs some more work to fully support old/new tools matrix.
- Addressed Dave's comment about bool usage in patch
  "RDS: IB: track and log active side..."

v1->v2:
Re-aligned indentation in patch 'RDS: mark few internal functions..."

Series consist of:
 - RDMA transport fixes for map failure, listen sequence, handler panic and
   composite message notification.
 - Couple of sparse fixes.
 - Message logging improvements for bind failure, use once mr semantics
   and connection remote address, active end point.
 - Performance improvement for RDMA transport by reducing the post send
   pressure on the queue and spreading the CQ vectors.
 - Useful statistics for socket send/recv usage and receive cache usage.
 - Additional RDS CMSG used by application to track the RDS message
   stages for certain type of traffic to find out latency spots.
   Can be enabled/disabled per socket.
