Subject: [PATCH mm 09/11] kasan: export kasan_poison as GPL
Date: Thu, 21 Dec 2023 21:04:51 +0100 [thread overview]
Message-ID: <171d0b8b2e807d04cca74f973830f9b169e06fb8.1703188911.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1703188911.git.andreyknvl@google.com>
From: Andrey Konovalov <andreyknvl@google.com>
KASAN uses EXPORT_SYMBOL_GPL for symbols whose exporting is only required
for KASAN tests when they are built as a module.
kasan_poison is one on those symbols, so export it as GPL.
