[GIT PULL] Block fixes for 4.2-rc2

[Jens Axboe <axboe@fb.com>]

Hi Linus,

A collection of fixes from the last few weeks that should go into the
current series. This pull request contains:

- Various fixes for the per-blkcg policy data, fixing regressions since
  4.1 From Arianna and Tejun.

- Code cleanup for bcache closure macros from me. Really just flushing
  this out, it's been sitting in another branch for months.

- FIELD_SIZEOF cleanup from Maninder Singh.

- bio integrity oops fix from Mike.

- Timeout regression fix for blk-mq from Ming Lei.

Please pull!
