[PATCH v4 0/8] connect reject event helpers

[swise@opengridcomputing.com (Steve Wise)]

While reviewing:

http://lists.infradead.org/pipermail/linux-nvme/2016-October/006681.html

I decided to propose transport-agnostic helper functions to better
handle connection reject event information.  Included are patches
for nvme/fabrics, iser, and rds to utilize the new helpers.

Doug, this series applies on top of v4.9-rc2 as well as sagi's nvmf-4.9-rc
branch as of today.  The series should be targeted for 4.10.

Changes since v3:
- added reviewed-by/acked-by tags
- positive logic in reject_msg helpers
- cleaned up reject message strings
- added patches to use helpers in isert and nvmet_rdma
- fixed zero-day build warning

Changes since v2:

- reworked ibcm/iwcm_reject_msg() as per Christoph's recommendation
- use ibcm_ and iwcm_ prefix instead of ib_ and iw_ for reject_msg funcs
- change rdma_consumer_reject() to rdma_is_consumer_reject()
- add rdma_consumer_reject_data() helper function to return private
  data/len
- use new helpers in nvme_rdma, ib_iser, and rdma_rds
- in nvme_rdma, add strings for nvme_rdma_cm_status values
