Need to fix it, otherwise there are many false-positives. Fixed: 1. Enable stack checking with KASAN_OUTLINE 2. When fork process, then reset address tag for kernel stack, so that it will not have false-positives after KASAN initialization. 3. Disable stack instrumentation in init.c in order to avoid start_kernel() have some false-positives.
