      block: let io_schedule() flush the plug inline · a237c1c5

      Linus correctly observes that the most important dispatch cases
      are now done from kblockd, this isn't ideal for latency reasons.
      The original reason for switching dispatches out-of-line was to
      avoid too deep a stack, so by _only_ letting the "accidental"
      flush directly in schedule() be guarded by offload to kblockd,
      we should be able to get the best of both worlds.
      
      So add a blk_schedule_flush_plug() that offloads to kblockd,
      and only use that from the schedule() path.
