[net-next][PATCH v2 00/18] net: RDS updates

[Santosh Shilimkar <santosh.shilimkar@oracle.com>]

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.
   rds-tools already equipped to parse this info.
 - 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.
