Subject: [ANNOUNCEMENT] io_uring SQPOLL sharing changes
Date: Fri, 19 Mar 2021 15:48:04 +0000 [thread overview]
Message-ID: <ca41ede6-7040-5eac-f4f0-9467427b1589@gmail.com> (raw)
Hey,
You may have already noticed, but there will be a change how SQPOLL
is shared in 5.12. In particular, SQPOLL may be shared only by processes
belonging to the same thread group. If this condition is not fulfilled,
then it silently creates a new SQPOLL task.
Just FYI, but may also yield some discussion on the topic.
