Subject: [PATCH net-next 06/14] devlink: remove start variables from dumps
Date: Tue, 3 Jan 2023 20:16:28 -0800 [thread overview]
Message-ID: <20230104041636.226398-7-kuba@kernel.org> (raw)
In-Reply-To: <20230104041636.226398-1-kuba@kernel.org>
The start variables made the code clearer when we had to access
cb->args[0] directly, as the name args doesn't explain much.
Now that we use a structure to hold state this seems no longer
needed.
