Thanks, merged.

Out of curiosity, in the end you plan to use LTP shell tests? Although skipped
tests did not mention any shell test, we did not expect you'd be running it.
FYI tst_test.sh (aka "new API") is being slowly replaced by new "shell loader"
API [2] (or tests are rewritten in C).

I also wonder if you use our new runner kirk already [3].

Kind regards,
Petr
