From: Pavel Begunkov @ 2020-10-14 19:44 UTC (permalink / raw)
  To: Jens Axboe, io-uring

A naive test with io_uring-bench with [nops, submit/complete batch=32]
shows 5500 vs 8500 KIOPS. Not really representative but might hurt if
left without [1/2].

Pavel Begunkov (2):
  io_uring: optimise COMP_LOCK-less flush_completion
  io_uring: optimise io_fail_links()
