Subject[PATCH v2 2/2] Kconfig.debug: Provide a little extra FRAME_WARN leeway when KASAN is enabled
Date
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.
