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)"
