Subject: Feature Request: SQE's flag for when you are not interested in the op.result
Date: Wed, 22 Apr 2020 11:04:22 +0300 [thread overview]
Message-ID: <[email protected]> (raw)
When e.g manipulating epoll state via its FD, most of the time you don’t care wether e.g EPOLL_CTL_DEL succeeds or fails, or you know that it will “never” fail. In such cases maybe it ‘d be beneficial to support another IOSQE flag which, when set, would instruct the io_uring to not include a matching CQE for that SQE when processed.
It’s not a big deal, per se, but it would probably help somewhat with performance.
