We need to hack it a bit more to initialize rest of the memory as
well. This is what I did before I dropped the idea.

+static void setup(void)
+{
+       uint *temp;
+
+       openat2_supported_by_kernel();
+
+       temp = (uint *)(how + 1);
+       *temp = 0xDEAD;
+}
+
 static void run(unsigned int n)
 {
        struct tcase *tc = &tcases[n];

        .needs_tmpdir = 1,
        .bufs = (struct tst_buffers []) {

                {},
        }
 };
