I see a spurious dpdk-test fail for this, on per_lcore_autotest, it
remotely launches an lcore which is running though it should not be able
to. I threw the relevant blurbs below - I will bring this to Bugzilla since
obviously your patch is unrelated.
We can do a retest if you want - otherwise I think you are safe to ignore
this fail.
