Merge tag 'for-5.19/block-exec-2022-06-02' of git://git.kernel.dk/linux-block

Pull block request execute cleanups from Jens Axboe:
 "This change was advertised in the initial core block pull request, but
  didn't actually make that branch as we deferred it to a post-merge
  pull request to avoid a bunch of cross branch issues.

  This series cleans up the block execute path quite nicely"

* tag 'for-5.19/block-exec-2022-06-02' of git://git.kernel.dk/linux-block:
  blk-mq: remove the done argument to blk_execute_rq_nowait
  blk-mq: avoid a mess of casts for blk_end_sync_rq
  blk-mq: remove __blk_execute_rq_nowait
