Hi Alex,

Thanks for pointing it out.

"Patchew" also identified some errors which we are working on fixing for
the next version. Patchew summarized the errors in the following page:
https://patchew.org/QEMU/address@hidden/

To confirm we're compliant with Patchew, we are running docker tests
before sending the patches for review next time around.

We'll use the following wiki to trigger "travis-ci" tests before pushing
the branch for review next time around:
https://wiki.qemu.org/Testing/CI/Travis#Testing_Changes_to_Travis

Are shippable, stsquad & cirrus-ci redundant if travis-ci & docker tests
pass?

Thank you very much!
