Thanks Anatoly's review.
I also prefer keep unlock in one place.
As a new guy, finally I choose just a fix with a minor change. I would do better next time.
And could I ask you one question, Anatoly?
I sent another dpdk patch with wrong git-send-email command, "git send-email -1 --to dev at dpdk.org patch_xxxx".
As a result, it generated another wrong reply and email thread.
I don't know if i need to send v2 patch to correct it then?
Its url is https://www.mail-archive.com/dev@dpdk.org/msg119925.html.
Best Regards
Feng
