[GIT PULL] nvme update for Linux 4.14, take 2

[Christoph Hellwig]

Hi Jens,

below is the current set of NVMe updates for Linux 4.14, now against your
postmerge branch, and with three more patches.

The biggest bit comes from Sagi and refactors the RDMA driver to prepare
for more code sharing in the setup and teardown path.  But we have various
features and bug fixes from a lot of people as well.

The following changes since commit cd996fb47c360320cf25ac9503c16de085ea9cfc:

  Merge tag 'v4.13-rc7' into for-4.14/block-postmerge (2017-08-28 13:00:44 -0600)

are available in the git repository at:
