Andrey Konovalov 6a63a63ff1 kasan: introduce CONFIG_KASAN_HW_TAGS ... This patch adds a configuration option for a new KASAN mode called hardware tag-based KASAN. This mode uses the memory tagging approach like the software tag-based mode, but relies on arm64 Memory Tagging Extension feature for tag management and access checking.
