Subject: [PATCH v4 14/22] kmsan: use stack_depot_save instead of __stack_depot_save
Date: Mon, 20 Nov 2023 18:47:12 +0100 [thread overview]
Message-ID: <18092240699efdc6acd78b51e41ea782953e6c8d.1700502145.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1700502145.git.andreyknvl@google.com>
From: Andrey Konovalov <andreyknvl@google.com>
Make KMSAN use stack_depot_save instead of __stack_depot_save,
as it always passes true to __stack_depot_save as the last argument.
