Hello, I was doing some kasan-related debugging and when I enabled it I started getting warnings for large stackframes. So CONFIG_FRAME_WARN has : int "Warn for stack frames larger than (needs gcc 4.4)" range 0 8192 default 0 if KASAN default 2048 if GCC_PLUGIN_LATENT_ENTROPY default 1024 if !64BIT default 2048 if 64BIT This means that frame_warns should effectively be disabled when kasan is enabled. However in my case this is not the situation. http://sprunge.us/FiGf here is the config file. It does have CONFIG_KASAN=y and CONFIG_FRAME_WARN=1024 . And even this is erroneous since it's a 64bit kernel, so it should be 2k. I haven't manually set the limit to 1k either.
