Subject: [GIT PULL] Block fixes for 4.5-rc

Hi Linus,

A collection of fixes from the past few weeks that should go into 4.5.
This pull request contains:

- Overflow fix for sysfs discard show function from Alan.

- A stacking limit init fix for max_dev_sectors, so we don't end up
  artificially capping some use cases. From Keith.

- Have blk-mq proper end unstarted requests on a dying queue, instead of
  pushing that to the driver. From Keith.

- NVMe
        - Update to Kconfig description for NVME_SCSI, since it was
          vague and having it on is important for some SUSE distros.
          From Christoph.
        - Set of fixes from Keith, around surprise removal. Also kills
          the no-merge flag, so it supports merging.

- Set of fixes for lightnvm from Matias, Javier, and Wenwei.

- Fix null_blk oops when asked for lightnvm, but not available. From
  Matias.

- Copy-to-user EINTR fix from Hannes, fixing a case where SG_IO fails if
  interrupted by a signal.

- Two floppy fixes from Jiri, fixing signal handling and blocking open.

- A use-after-free fix for O_DIRECT, from Mike Krinkin.

- A block module ref count fix from Roman Pen.

- An fs IO wait accounting fix for O_DSYNC from Stephane Gasparini.

- Smaller reallo fix for xen-blkfront from Bob Liu.

- Removal of an unused struct member in the deadline IO scheduler, from
  Tahsin.

- Also from Tahsin, properly initialize inode struct members associated
  with cgroup writeback, if enabled.

- From Tejun, ensure that we keep the superblock pinned during cgroup
  writeback.


Please pull!
