[GIT PULL] Block fixes for 4.4-rc

[Jens Axboe <axboe@fb.com>]

Hi Linus,

A set of fixes for the current series. This pull request contains:

- A bunch of fixes for lightnvm, should be the last round for this
  series. From Matias and Wenwei.

- A writeback detach inode fix from Ilya, also marked for stable.

- A block (though it says SCSI) fix for an OOPS in SCSI runtime power
  management.

- Module init error path fixes for null_blk from Minfei.

Please pull!
