How can we call tst_brk_() via tst_res_() ?
	tst_res_(argv[1], atoi(argv[2]), type, "%s", msg);

Also we have TST_RES_SUPPORTS_TCONF_TDEBUG_TFAIL_TINFO_TPASS_TWARN check to not
add TBROK to tst_res_().

...

> +		type = TBROK;
> +	} else {
> +		printf("Wrong type '%s'\n", argv[3]);
>  		goto help;

Also tst_brk allows only TBROK and TCONF in C:

#define tst_brk(ttype, arg_fmt, ...)						\
	({									\
		TST_BRK_SUPPORTS_ONLY_TCONF_TBROK(!((ttype) &			\
			(TBROK | TCONF | TFAIL)));				\
		tst_brk_(__FILE__, __LINE__, (ttype), (arg_fmt), ##__VA_ARGS__);\
	})

... and shell:

	if [ "$res" != TBROK -a "$res" != TCONF ]; then
		tst_res TBROK "tst_brk can be called only with TBROK or TCONF ($res)"
	else
		tst_res "$res" "$@"
	fi

Kind regards,
