Subject: [RFC v2 0/2] non-atomic req->refs
Date: Thu, 29 Apr 2021 18:20:40 +0100 [thread overview]
Message-ID: <cover.1619716401.git.asml.silence@gmail.com> (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.
v2: wrong patch with inverted an req_ref_sub_and_test() condition
Pavel Begunkov (2):
io_uring: defer submission ref put
io_uring: non-atomic request refs
