Merge branch 'for-4.2/drivers' of git://git.kernel.dk/linux-block
Pull block driver updates from Jens Axboe:
"This 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"
