Turns out that this isn't a new problem and include/event.h already
had a work around by adding the 'used' attribute that I copied.

Sorting out the rebase, the tests look better locally, up until they
ask to run as root, which I don't feel comfortable with, so I am
sending it to the CI for more complete coverage.
