[LTP] [PATCH] tst_test_macros.h: Add TST_EXP_VAL macro

[Li Wang]

Hi Lianjie,

Some queries:

Do we have test scenarios for making use of these macros?

And can you write a test to verify the macros you added at the same time?
(just like what we had done in test_macros0*.c)

Btw, you should keep the code indent consistent with the original.
(especially for backlash \)
