#     Pull block fixes from Jens Axboe:
#      "A few fixes that should make it into this release. This contains:
#     
#        - io_uring:
#             - The timeout command assumes sequence == 0 means that we want
#               one completion, but this kind of overloading is unfortunate as
#               it prevents users from doing a pure time based wait. Since
#               this operation was introduced in this cycle, let's correct it
#               now, while we can. (me)
#             - One-liner to fix an issue with dependent links and fixed
#               buffer reads. The actual IO completed fine, but the link got
#               severed since we stored the wrong expected value. (me)
#             - Add TIMEOUT to list of opcodes that don't need a file. (Pavel)
#     
#        - rsxx missing workqueue destry calls. Old bug. (Chuhong)
#     
#        - Fix blk-iocost active list check (Jiufei)
#     
#        - Fix impossible-to-hit overflow merge condition, that still hit some
#          folks very rarely (Junichi)
#     
#        - Fix bfq hang issue from 5.3. This didn't get marked for stable, but
#          will go into stable post this merge (Paolo)"

#       rsxx: add missed destroy_workqueue calls in remove

#       io_uring: Fix getting file for timeout
#       block: check bi_size overflow before merge
#       io_uring: make timeout sequence == 0 mean no sequence
