Subject: [RFC 0/2] non-atomic req->refs
Date: Thu, 29 Apr 2021 17:39:03 +0100 [thread overview]
Message-ID: <[email protected]> (raw)
[knowingly buggy, don't use]
Just a glimpse on the de-atomising request refcounting for benchmarking,
dirty and with a bunch of known problems (in [a]poll and iopoll).
Haven't got any perf numbers myself yet.
Pavel Begunkov (2):
io_uring: defer submission ref put
io_uring: non-atomic request refs
