Subject: Re: [PATCH v4 6/7] rust: completion: add complete()
Date: Wed, 04 Nov 2026 23:11:11 +0000 [thread overview]
Message-ID: <sashiko-outbox-198272@kernel.org> (raw)
In-Reply-To: <20261105-b4-rust-pci-edu-driver-v4-6-20ef027bb707@mailbox.org>
> The initial completion abstraction only added `complete_all()` and
> `wait_for_completion()`. `complete_all()` marks the completion permanently
> done, which makes a single `Completion` unsuitable for signalling the same
> event repeatedly: once `complete_all()` has run, every subsequent
> `wait_for_completion()` returns immediately without waiting.
>
> Add `complete()`, which wakes a single waiter and increments the internal
> counter by one. Paired one-to-one with `wait_for_completion()`, it allows
> the same completion to be reused across multiple cycles, e.g. to wait for
> consecutive DMA transfers to finish.
