Subject: Kconfig.debug: provide a little extra FRAME_WARN leeway when KASAN is enabled
Date: Fri, 25 Nov 2022 12:07:50 +0000
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.
