Testcase 1.3 - EINVAL: uninitialized iocb
is about submitting uninitialized iocb structure.
Test is expecting to get -EINVAL, but other values are also
possible as uninitialized struct can contain any values.
For example following data fails with -EBADF:
--- snip ---
unsigned char bad_iocb[64] = {
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x05, 0x84, 0xa5,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x0f, 0xff, 0xe0, 0x10, 0x0c, 0x30,
0x00, 0x00, 0x0f, 0xff, 0xe0, 0x10, 0x0c, 0x40,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
memcpy(&iocb, bad_iocb, sizeof(iocb));
iocbs[0] = &iocb;
TEST(io_submit(ctx, 1, iocbs));
check_result(-EINVAL, TEST_RETURN);
--- snip ---
This patch accepts also few other errno codes as valid return value.
