Subject: Re: [PATCH v3 4/5] rust: completion: add complete()
Date: Wed, 12 Aug 2026 19:56:07 +0000 [thread overview]
Message-ID: <20260812195608.627851F000E9@smtp.kernel.org> (raw)
In-Reply-To: <20260812-b4-rust-pci-edu-driver-v3-4-5d0b5594e52b@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.
