[ANNOUNCEMENT] io_uring SQPOLL sharing changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
