Merge branch 'for-4.1/core' of git://git.kernel.dk/linux-block
Pull block layer core bits from Jens Axboe: "This is the core pull request for 4.1. Not a lot of stuff in here for this round, mostly little fixes or optimizations. This pull request contains: - An optimization that speeds up queue runs on blk-mq, especially for the case where there's a large difference between nr_cpu_ids and the actual mapped software queues on a hardware queue. From Chong Yuan. - Honor node local allocations for requests on legacy devices. From David Rientjes. - Cleanup of blk_mq_rq_to_pdu() from me. - exit_aio() fixup from me, greatly speeding up exiting multiple IO contexts off exit_group(). For my particular test case, fio exit took ~6 seconds. A typical case of both exposing RCU grace periods to user space, and serializing exit of them. - Make blk_mq_queue_enter() honor the gfp mask passed in, so we only wait if __GFP_WAIT is set. From Keith Busch. - blk-mq exports and two added helpers from Mike Snitzer, which will be used by the dm-mq code. - Cleanups of blk-mq queue init from Wei Fang and Xiaoguang Wang" * 'for-4.1/core' of git://git.kernel.dk/linux-block: blk-mq: reduce unnecessary software queue looping aio: fix serial draining in exit_aio() blk-mq: cleanup blk_mq_rq_to_pdu() blk-mq: put blk_queue_rq_timeout together in blk_mq_init_queue() block: remove redundant check about 'set->nr_hw_queues' in blk_mq_alloc_tag_set() block: allocate request memory local to request queue blk-mq: don't wait in blk_mq_queue_enter() if __GFP_WAIT isn't set blk-mq: export blk_mq_run_hw_queues blk-mq: add blk_mq_init_allocated_queue and export blk_mq_register_disk
