I merged with these changes:

		if (errno == EOPNOTSUPP)
			tst_brk(TCONF, "CONFIG_IO_URING is not enabled");

* changed subject to: "tst_safe_io_uring.c: Check EOPNOTSUPP errno"
* Adjusted commit message (no io_uring_*() syscall will be working due
  CONFIG_IO_URING not enabled in the kernel).
* simplify if style

Thanks!

Kind regards,
Petr
