[GIT PULL] Block drivers bits for 4.1

[Jens Axboe <axboe@fb.com>]

Hi Linus,

This is the block driver pull request for 4.1. As with the core bits,
this is a relatively slow round. This pull request contains:

- Various fixes and cleanups for NVMe, from Alexey Khoroshilov, Chong
  Yuan, myself, Keith Busch, and Murali Iyer.

- Documentation and code cleanups for nbd from Markus Pargmann.

- Change of brd maintainer to me, from Ross Zwisler. At least the email
  doesn't bounce anymore then.

- Two xen-blkback fixes from Tao Chen.

Please pull!
