Subject: [RFC 4/6] io_uring/notif: remove ctx var from io_notif_tw_complete
Date: Fri, 12 Apr 2024 13:55:25 +0100	[thread overview]
Message-ID: <b69c65b1df421865057f285d6309faee0d327096.1712923998.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

We don't need ctx in the hottest path, i.e. registered buffers,
let's get it only when we need it.
