[PATCH RFC 0/4] sqsize zero-based fixes

[james_p_freyensee@linux.intel.com (Jay Freyensee)]

These patches are based on NVMe-over-Fabrics spec clarifcations
by Dave Minturn, one of the spec authors. 
In summary, sqsize and hsqsize are 0-based
values, and hrqsize cannot be smaller than hsqsize+1.

There is an issue with these patches I haven't worked out yet,
thus the reason for RFC.  The keep-alive timer is going
off then causes a kernel crash and I haven't worked out
exactly why yet, but I'm thinking
it has something to do with sqsize now being 0-based but
the RDMA implemenation layer's queue_size being 1's based.

Anyways, feedback appreciated as I continue
to work on how to fix this appropriately.

Jay Freyensee (4):
  fabrics: define admin sqsize min default, per spec
  nvme-rdma: fix sqsize/hsqsize/hrqsize per spec
  nvmet-rdma: +1 to *queue_size from hsqsize/hrqsize
  nvme-loop: set sqsize to 0-based value, per spec
