For 4.5, I'd like to address the send queue accounting and
invalidation/unmap ordering issues Jason brought up a couple of
months ago.

In preparation for Doug's final topic branch, Anna, I've rebased
these on Christoph's ib_device_attr branch, but there were no merge
conflicts or other changes needed. Could you begin preparing these
for linux-next and other final testing and review?

Also available in the "nfs-rdma-for-4.5" topic branch of this git repo:

git://git.linux-nfs.org/projects/cel/cel-2.6.git

Or for browsing:

Changes since v2:
- Rebased on Christoph's ib_device_attr branch


Changes since v1:

- Rebased on v4.4-rc3
- Receive buffer safety margin patch dropped
- Backchannel pr_err and pr_info converted to dprintk
- Backchannel spin locks converted to work queue-safe locks
- Fixed premature release of backchannel request buffer
- NFSv4.1 callbacks tested with for-4.5 server
