Subject: [PATCH 08/11] trace2: avoid "futile conditional"
Date: Thu, 15 May 2025 13:11:46 +0000 [thread overview]
Message-ID: <a3f60183633eb17fb300309cf1a629234588418f.1747314709.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1891.git.1747314709.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
CodeQL reports empty `if` blocks that only contain a comment as "futile
conditional". The comment talks about potential plans to turn this into
a warning, but that seems not to have been necessary. Replace the entire
construct with a concise comment.
