// Make sure the sanitize_address attribute is emitted when using ASan, KASan or
// HWASan. Either __attribute__((no_sanitize("address")) or
// __attribute__((no_sanitize("kernel-address")) disables both ASan and KASan
// instrumentation.
// Same for __attribute__((no_sanitize("hwaddress")) and
// __attribute__((no_sanitize("kernel-hwddress")) and HWASan and KHWASan.
