#     Pull block fixes from Jens Axboe:
#      "A few block fixes for this release:
#     
#        - Revert a BFQ commit that causes breakage for people. Unfortunately
#          it was auto-selected for stable as well, so now 5.14.7 suffers from
#          it too. Hopefully stable will pick up this revert quickly too, so
#          we can remove the issue on that end as well.
#     
#        - Add a quirk for Apple NVMe controllers, which due to their
#          non-compliance broke due to the introduction of command sequences
#          (Keith)
#     
#        - Use shifts in nbd, fixing a __divdi3 issue (Nick)"
#     
#     * tag 'block-5.15-2021-10-01' of git://git.kernel.dk/linux-block:
#       nbd: use shifts rather than multiplies
#       Revert "block, bfq: honor already-setup queue merges"
#       nvme: add command id quirk for apple controllers
