[GIT PULL] Block fixes for 4.5-final

[Jens Axboe <axboe@fb.com>]

Hi Linus,

A set of fixes for 4.5-rc6 - it's a lot bigger than I would like at this
point, but there's really nothing in here that we should not merge for
4.5 final - with a possible exception being a few of the lightnvm fixes,
that has a cleanup part before a fix, and the cgroup writeback enable
for block devices from Shaohua (which we'd like to get into 4.5 final).
The grunt of it should have gone in last week, but continued bug fixing
for NVMe meant that it got pushed to this week.

In details, this pull request contains:

- Various fixes for lightnvm, from Alan, Javier, and Matias.

- Three bug fixes for xen blk-front/back from Jan Beulich, and Konrad.

- Extensive set of fixes for NVMe, fixing hot unplug problems and a
  regression in length of user commands supported. From Keith and
  Christoph, single fix from me.

- blk-mq potential oops fix in tag depth updates, from Keith.

- A fix for an umount with cgroup writeback regression in this series
  from Tejun.

- Enable block device cgroup writeback, from Shaohua. The grunt of the
  code for accounting was already there, this just enables it.

- Set of 4 patches for the block core on merging, from Ming Lei.

Please pull!
