#     Pull block fixes from Jens Axboe:
#      "Set of fixes that should go into this round. This pull is larger than
#       I'd like at this time, but there's really no specific reason for that.
#       Some are fixes for issues that went into this merge window, others are
#       not. Anyway, this contains:
#     
#        - Hardware queue limiting for virtio-blk/scsi (Dongli)
#     
#        - Multi-page bvec fixes for lightnvm pblk
#     
#        - Multi-bio dio error fix (Jason)
#     
#        - Remove the cache hint from the io_uring tool side, since we didn't
#          move forward with that (me)
#     
#        - Make io_uring SETUP_SQPOLL root restricted (me)
#     
#        - Fix leak of page in error handling for pc requests (Jérôme)
#     
#        - Fix BFQ regression introduced in this merge window (Paolo)
#     
#        - Fix break logic for bio segment iteration (Ming)
#     
#        - Fix NVMe cancel request error handling (Ming)
#     
#        - NVMe pull request with two fixes (Christoph):
#            - fix the initial CSN for nvme-fc (James)
#            - handle log page offsets properly in the target (Keith)"
#     
#     * tag 'for-linus-20190412' of git://git.kernel.dk/linux-block:
#       block: fix the return errno for direct IO
#       nvmet: fix discover log page when offsets are used
#       nvme-fc: correct csn initialization and increments on error
#       block: do not leak memory in bio_copy_user_iov()
#       lightnvm: pblk: fix crash in pblk_end_partial_read due to multipage bvecs
#       nvme: cancel request synchronously
#       blk-mq: introduce blk_mq_complete_request_sync()
#       scsi: virtio_scsi: limit number of hw queues by nr_cpu_ids
#       virtio-blk: limit number of hw queues by nr_cpu_ids
#       block, bfq: fix use after free in bfq_bfqq_expire
#       io_uring: restrict IORING_SETUP_SQPOLL to root
#       tools/io_uring: remove IOCQE_FLAG_CACHEHIT
#       block: don't use for-inside-for in bio_for_each_segment_all
