Subject: [PATCH v2 2/2] Kconfig.debug: Provide a little extra FRAME_WARN leeway when KASAN is enabled
Date: Fri, 25 Nov 2022 12:07:50 +0000 [thread overview]
Message-ID: <20221125120750.3537134-3-lee@kernel.org> (raw)
In-Reply-To: <20221125120750.3537134-1-lee@kernel.org>
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.
