Recent failure in autotest

The blacklist/whitelist documentation patch which is totally unrelated to this failed in the unit test. Looks like recent cmdline changes caused a problem?

Test Debug

This PANIC is usually expected... and is part of the check for rte_panic. And looking at your series, the associated test passes fine (see below for full trace).

On the other hand, your series breaks the unit test on the -w option. This is why the CI (UNH and Travis) flagged your series.
