I didn't understand that. Yes, you don't have shadow for shadow. But, for shadow addresses you return return (void *)kasan_zero_page in kasan_mem_to_shadow(), so we should be fine to access shadow in generic code. And with kasan_tracks_vaddr(), this should work too. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
