Subject: [GIT PULL] Block driver updates for 3.19

Hi Linus,

Below is the block driver pull request for 3.19, it sits on top of the
core pull request submitted yesterday. It contains:

- NVMe updates

        - The blk-mq conversion from Matias (and others)

        - A stack of NVMe bug fixes from the nvme tree, mostly from Keith.

        - Various bug fixes from me, fixing issues in both the blk-mq
          conversion and generic bugs.

        - Abort and CPU online fix from Sam.

        - Hot add/remove fix from Indraneel.

- A couple of drbd fixes from the drbd team (Andreas, Lars, Philipp)

- With the generic IO stat accounting from 3.19/core, converting md,
  bcache, and rsxx to use those. From Gu Zheng.

- Boundary check for queue/irq mode for null_blk from Matias. Fixes
  cases where invalid values could be given, causing the device to hang.

- The xen blkfront pull request, with two bug fixes from Vitaly.

Please pull!
