Subject: [PATCH 0/2] post F_COMP_LOCKED optimisations
Date: Wed, 14 Oct 2020 20:44:20 +0100 [thread overview]
Message-ID: <cover.1602703669.git.asml.silence@gmail.com> (raw)
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()
