Patch was accepted, please rebase. Also, please add at least one test which
uses it.

Also, I wonder if we need TST_EXP_PASS_PTR().

Maybe follow the pattern of already used tests (break saves else clause)?
 		if (TST_ERR != (ERRNO)) {                                      \
			TST_MSGP_(TFAIL | TTERRNO, " expected %s",             \

			break;                                                 \
		}                                                              \
                                                                               \
		TST_PASS = 1;                                                  \
