[LTP] [PATCH] lib: tst_has_slow_kconfig() cache the result

[Petr Vorel]

Hi Cyril, Li,


> The result from the tst_has_slow_kconfig() is not going to change so we

> end up being called. For instance any test that calls SAFE_CLONE() will
> call the function repeatedly. This change makes the tests slightly
> faster and also avoids repeated messages in the test output.

Thanks, elegant solution, thanks!
