Subject: [PATCH for-next 0/4] singly linked list for chains
Date: Thu, 15 Oct 2020 22:11:20 +0100 [thread overview]
Message-ID: <cover.1602795685.git.asml.silence@gmail.com> (raw)
see [3/4] and [4/4] for motivation, the other two are just preps.
I wasn't expecting to find performance difference, but my naive nop
test yeilds 5030 vs 5160 KIOPS, before and after [3/4] correspondingly.
The test is submitting 32 linked nops and waits for them to complete.
The testing is tuned for consistentcy, and the results are consistent
across reboots.
Pavel Begunkov (4):
io_uring: inline io_fail_links()
io_uring: simplify linked timeout cancel
io_uring: link requests with singly linked list
io_uring: toss io_kiocb fields for better caching
