I'm a bit worried about the size of the patch and I would like to see it split
up for review. But I agree Christophs method is better long term.

to 1m pool till 8k pool recovers for use.
This helps to at least push ~55 kB/s bidirectional data which
is a nice improvement.

mutual exclusion locks are being performed.
In next patch, send completion is also split which re-uses the poll_cq()
and hence the code is moved to ib_cm.c

All HCA drivers seems to popullate max_mr caps and few of
them do both max_mr and max_fmr.
Hence update RDS code to make use of max_mr.

synchronize_rcu() slowing down un-necessarily the socket shutdown
path. It is used just kfree() the ip addresses in rds_ib_remove_ipaddr()
which is perfect usecase for kfree_rcu();
So lets use that to gain some speedup.

As a side note, the IB HCA driver I used for testing misses at least 3
important patches in upstream to see the full blown IB performance and
am hoping to get that in mainline with help of them.

This series addresses RDS connection bottlenecks on massive workloads and

RDS is being used in massive systems
as expected.
The rds change looks also straight forward since ib_get_dma_mr()
is being used for local write.
So feel free to add below tag if you need one.
