Subject: [PATCH mm 14/22] kasan: merge __kasan_report into kasan_report
Date:   Wed,  2 Mar 2022 17:36:34 +0100
Message-Id: <c8a125497ef82f7042b3795918dffb81a85a878e.1646237226.git.andreyknvl@google.com>

From: Andrey Konovalov <andreyknvl@google.com>

Merge __kasan_report() into kasan_report(). The code is simple enough
to be readable without the __kasan_report() helper.
