Subject: linux-next: build failure after merge of the rdma tree

Hi all,

After merging the rdma tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from /home/sfr/next/next/include/rdma/rdma_counter.h:12,
                 from <command-line>:
/home/sfr/next/next/include/rdma/ib_verbs.h:2126:27: error: field 'port_counter' has incomplete type
  struct rdma_port_counter port_counter;
                           ^~~~~~~~~~~~

Caused by commit

  413d3347503b ("RDMA/counter: Add set/clear per-port auto mode support")

rdma_counter.h include ib_verbs.h which in turn needs rdma_port_counter
from rdma_counter.h, but it is not defined yet :-(

I have applied the following patch for today.

Subject: [PATCH] RDMA: don't try to build rdma_counter.h for now

rdma_counter.h include ib_verbs.h which in turn needs rdma_port_counter
from rdma_counter.h, but it is not defined yet :-(
