   2 // HWASan. Either __attribute__((no_sanitize("address")) or
   3 // __attribute__((no_sanitize("kernel-address")) disables both ASan and KASan
   4 // instrumentation.
   5 // Same for __attribute__((no_sanitize("hwaddress")) and
   6 // __attribute__((no_sanitize("kernel-hwddress")) and HWASan and KHWASan.
