[GIT PULL] nvme updates for Linux 4.15

[Christoph Hellwig <hch@infradead.org>]

Hi Jens,

below are the currently queue nvme updates for Linux 4.15.  There are
a few more things that could make it for this merge window, but I'd
like to get things into linux-next, especially for the unlikely case
that Linus decided to cut -rc8.

Highlights:
 - support for SGLs in the PCIe driver (Chaitanya Kulkarni)
 - disable I/O schedulers for the admin queue (Israel Rukshin)
 - various Fibre Channel fixes and enhancements (James Smart)
 - various refactoring for better code sharing between transports
   (Sagi Grimberg and me)

as well as lots of little bits from various contributors.

The following changes since commit 9c9883744dda1cc38339a448dd8435140537027e:

  block: move __elv_next_request to blk-core.c (2017-10-03 08:43:04 -0600)

are available in the git repository at:
