Message-ID: <20240904091451.3328272-2-lihongbo22@huawei.com> Date: Wed, 4 Sep 2024 17:14:43 +0800 From: Hongbo Li <lihongbo22@...wei.com> To: <kees@...nel.org>, <andy@...nel.org>, <Julia.Lawall@...ia.fr>, <nicolas.palix@...g.fr> CC: <linux-hardening@...r.kernel.org>, <cocci@...ia.fr>, <lihongbo22@...wei.com> Subject: [PATCH -next v2 1/9] coccinelle: Add rules to find str_true_false() replacements After str_true_false() has been introduced in the tree, we can add rules for finding places where str_true_false() can be used. A simple test can find over 10 locations.
