Merge branch 'for-3.12/core' of git://git.kernel.dk/linux-block
Pull block IO fixes from Jens Axboe: "After merge window, no new stuff this time only a collection of neatly confined and simple fixes" * 'for-3.12/core' of git://git.kernel.dk/linux-block: cfq: explicitly use 64bit divide operation for 64bit arguments block: Add nr_bios to block_rq_remap tracepoint If the queue is dying then we only call the rq->end_io callout. This leaves bios setup on the request, because the caller assumes when the blk_execute_rq_nowait/blk_execute_rq call has completed that the rq->bios have been cleaned up. bio-integrity: Fix use of bs->bio_integrity_pool after free blkcg: relocate root_blkg setting and clearing block: Convert kmalloc_node(...GFP_ZERO...) to kzalloc_node(...) block: trace all devices plug operation
