[GIT PULL] Block drivers updates for 4.4

[Jens Axboe]

Hi Linus,

On top of the core block bits, here are the block driver changes for
4.4. This pull request contains:

- NVMe:
        - Refactor and moving of code to prepare for proper target
          support. From Christoph and Jay.

        - 32-bit nvme warning fix from Arnd.

        - Error initialization fix from me.

        - Proper namespace removal and reference counting support from
          Keith.

        - Device resume fix on IO failure, also from Keith.

        - Dependency fix from Keith, now that nvme isn't under the
          umbrella of the block anymore.

        - Target location and maintainers update from Jay.

- From Ming Lei, the long awaited DIO/AIO support for loop.

- Enable BD-RE writeable opens, from Georgios.

Please pull!
