Subject: [PATCH] Kconfig.debug: provide a little extra FRAME_WARN leeway when
KASAN is enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When enabled, KASAN enlarges function's stack-frames. Pushing quite a few
over the current threshold. This can mainly be seen on 32-bit
architectures where the present limit (when !GCC) is a lowly 1024-Bytes.
