#     Merge tag 'block-5.14-2021-07-30' of git://git.kernel.dk/linux-block
#     
#     Pull block fixes from Jens Axboe:
#     
#      - gendisk freeing fix (Christoph)
#     
#      - blk-iocost wake ordering fix (Tejun)
#     
#      - tag allocation error handling fix (John)
#     
#      - loop locking fix. While this isn't the prettiest fix in the world,
#        nobody has any good alternatives for 5.14. Something to likely
#        revisit for 5.15. (Tetsuo)
#
