Merge branch 'for-4.5/nvme' of git://git.kernel.dk/linux-block
Pull NVMe updates from Jens Axboe:
"Last branch for this series is the nvme changes. It's in a separate
branch to avoid splitting too much between core and NVMe changes,
since NVMe is still helping drive some blk-mq changes. That said, not
a huge amount of core changes in here. The grunt of the work is the
continued split of the code"
