This seems to always indicate that my gcc doesn't support
-fsanitize=kernel-address:
Makefile:769: Cannot use CONFIG_KASAN: -fsanitize=kernel-address not supported by compiler
Even though:
$ gcc --version

$ cat test.c
#include <stdio.h>
#include <sys/mman.h>
void __asan_init_v3(void) { }
int main(int argc, char *argv[])
{
return 0;
}
$ gcc -fsanitize=kernel-address test.c
$ ./a.out
