in debian/changelog there should be an entery for 9.10... i guess the change entries could be somewhere else, but building the pkg, it gets confusing if you install the resulting .deb and dpkg -l shows wrong version.
Yeah, I don't really grok .deb stuff, so I'm not sure what I should be distributing
in the debian directory, and what I should leave to the much more capable Stephen Gran
who is the debian Packager for hdparm.
For now, I'll just nuke that file completely.
