Subject: [PATCH 15/16] io_uring: correct fill events helpers types
Date: Mon, 4 Oct 2021 20:03:00 +0100 [thread overview]
Message-ID: <7ca6f15255e9117eae28adcac272744cae29b113.1633373302.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
CQE result is a 32-bit integer, so the functions generating CQEs are
better to accept not long but ints. Convert io_cqring_fill_event() and
other helpers.
