Maybe at some point we should replace exclusions based on GCC_PLUGINS_CFLAGS and KASAN_SANITIZE and UBSAN_SANITIZE and OBJECT_FILES_NON_STANDARD and so on with something more generic... something that says "this file will not be built into the normal kernel, it contains code that runs in realmode / userspace / some similarly weird context, and none of our instrumentation infrastructure is available there"...Good idea. I would also add 'notrace' to that list.
Hm? notrace code should definitely still be subject to sanitizer instrumentation. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
