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

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.

RDS: IB: fix panic due to handlers running post teardown

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 before freeing
cq/qp resources so as such the handlers have nothing left
to do post shutdown.

On other hand any handler running after teardown and trying
to access already freed qp/cq resources causes issues
Patch fixes this race by makes sure that handlers returns
without any action post teardown.
