[GIT PULL] Block driver pull request for 4.2

[Jens Axboe]

Hi Linus,

This is the block driver pull request for 4.2. It depends on the
previously sent core pull request. This pull request contains:

- A few race fixes for null_blk, from Akinobu Mita.

- A series of fixes for mtip32xx, from Asai Thambi and Selvan Mani at
  Micron.

- NVMe:

	- Fix for missing error return on allocation failure, from Axel
	  Lin.

	- Code consolidation and cleanups from Christoph.

	- Memory barrier addition, syncing queue count and queue
	  pointers. From Jon Derrick.

	- Various fixes from Keith, an addition to support user
	  issue reset from sysfs or ioctl, and automatic namespace
	  rescan.

	- Fix from Matias, avoiding losing some request flags when
	  marking the request failfast.

- Small cleanups and sparse fixups for ps3vram. From Geert Uytterhoeven
  and Geoff Lavand.

- s390/dasd dead code removal, from Jarod Wilson.

- A set of fixes and optimizations for loop, from Ming Lei.

- Conversion to blkdev_reread_part() of loop, dasd, ndb. From Ming Lei.

- Updates to cciss. From Tomas Henzl.


Please pull!

Andrew, it seems your fix for gcc never went in. I am hitting it in
Linus' tree.

Thanks,

Not sure why Andrew hasn't sent it in yet. Andrew, you planning on doing 
that, I did see it get queued up? If not, I can funnel it through my 
tree for 4.2.
