I have started seeing these objtool warnings from a wide variety of KASAN-enabled rcutorture-related test scenarios in next-20230125. It has been awhile since I tested -next, so I am not yet sure where this started. vmlinux.o: warning: objtool: __asan_memset+0x34: call to __memset() with UACCESS enabled vmlinux.o: warning: objtool: __asan_memmove+0x4d: call to __memmove() with UACCESS enabled vmlinux.o: warning: objtool: __asan_memcpy+0x4d: call to __memcpy() with UACCESS enabled As usual, should I be worried? Thanx, Paul
