Thanks, merged as
https://github.com/linux-test-project/kirk/commit/5e8c8064a0b2cee465f2a1dca1cfebef5ade36a2

BTW I wonder if recent kirk commits (SSH fixes) are strong enough to release
kirk and update LTP. WDYT? Or do you wait for ltx improvements before releasing
new version?

Kind regards,
Petr
