Yeoreum Yun 2616a517f9 kunit: kasan_test: disable fortify string checker on kasan_strings() test ... commit 7a19afee6f upstream. Similar to commit 09c6304e38 ("kasan: test: fix compatibility with FORTIFY_SOURCE") the kernel is panicing in kasan_string(). This is due to the `src` and `ptr` not being hidden from the optimizer which would disable the runtime fortify string checker.
