  dm, dax: Make sure dm_dax_flush() is called if device supports it (2017-07-26 15:55:44 -0400)

Please pull, thanks.

----------------------------------------------------------------
- A few DM integrity fixes that improve performance.  One that address
  inefficiencies in the on-disk journal device layout.  Another that
  makes use of the block layer's on-stack plugging when writing the
  journal.

- A dm-bufio fix for the blk_status_t conversion that went in during the
  merge window.

- A few DM raid fixes that address correctness when suspending the
  device and a validation fix for validation that occurs during device
  activation.

- A couple DM zoned target fixes.  Important one being the fix to not
  use GFP_KERNEL in the IO path due to concerns about deadlock in
  low-memory conditions (e.g. swap over a DM zoned device, etc).

- A DM DAX device fix to make sure dm_dax_flush() is called if the
  underlying DAX device is operating as a write cache.
