Hi Linus,

A collection of fixes since the merge window. This pull request
contains:

- Fix for a double elevator module release, from Chao Yu. Ancient bug.

- The splice() MORE flag fix from Christophe Leroy.

- A fix for NVMe, fixing a patch that went in in the merge window. From
  Keith.

- Two fixes for blk-mq CPU hotplug handling, from Ming Lei.

- bdi vs blockdev lifetime fix from Neil Brown, fixing and oops in md.

- Two blk-mq fixes from Shaohua, fixing a race on queue stop and a bad
  merge issue with FUA writes.

- Division-by-zero fix for writeback from Tejun.

- A block bounce page accounting fix, making sure we inc/dec after
  bouncing so that pre/post IO pages match up. From Wang YanQing.

Please pull!

[GIT PULL] Block fixes for 4.1-rc

Hi Linus,

Sending this off now, as I'm not aware of other current bugs, nor do I
expect further fixes before 4.1 final. This pull request contains two
fixes:

- A fix for a bdi unregister warning that gets spewed on md, due to a
  regression introduced earlier in this cycle. From Neil Brown.

- A fix for a compile warning for NVMe on 32-bit platforms, also a
  regression introduced in this cycle. From Arnd Bergmann.

Please pull!

Hi Linus,

Three small fixes that have been picked up the last few weeks.
Specifically:

- Fix a memory corruption issue in NVMe with malignant user constructed
  request. From Christoph.

- Kill (now) unused blk_queue_bio(), dm was changed to not need this
  anymore. From Mike Snitzer.

- Always use blk_schedule_flush_plug() from the io_schedule() path when
  flushing a plug, fixing a !TASK_RUNNING warning with md. From Shaohua.

Please pull!
