Hello, I've been working on this already and a different approach with the Kconfig ARCH_DEFER_KASAN has been proposed. Please see v4 thread. https://lore.kernel.org/all/20250805142622.560992-1-snovit...@gmail.com/ It also covers the printing in a single KASAN codebase, instead of printing "KASAN intiilaized" in arch/* code. Also covers the enabling KASAN via kasan_enable() for all 3 modes. It's up to KASAN maintainers to choose either version. I just need the confirmation now if I should proceed with v5, or your version if it covers all arch and cases should be picked up.
