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" * 'for-4.2/drivers' of git://git.kernel.dk/linux-block: (44 commits) mtip32xx: Fix accessing freed memory block: nvme-scsi: Catch kcalloc failure NVMe: Fix IO for extended metadata formats nvme: don't overwrite req->cmd_flags on sync cmd mtip32xx: increase wait time for hba reset mtip32xx: fix minor number mtip32xx: remove unnecessary sleep in mtip_ftl_rebuild_poll() mtip32xx: fix crash on surprise removal of the drive mtip32xx: Abort I/O during secure erase operation mtip32xx: fix incorrectly setting MTIP_DDF_SEC_LOCK_BIT mtip32xx: remove unused variable 'port->allocated' mtip32xx: fix rmmod issue MAINTAINERS: Update ps3vram block driver block/ps3vram: Remove obsolete reference to MTD block/ps3vram: Fix sparse warnings NVMe: Automatic namespace rescan NVMe: Memory barrier before queue_count is incremented NVMe: add sysfs and ioctl controller reset null_blk: restart request processing on completion handler null_blk: prevent timer handler running on a different CPU where started ...
