the pylint plugin is flagging some changes as failures when the pylint utility returns a success return code because of INFO level messages about local disables.
e.g. in a patch that removes all outstanding issues but has to use local disables in some cases, test-patch returns a -1 and the diff contains only:
In this particular case, the code uses dynamic attributes, which pylint in python 2.x can't handle. In general, things at the INFO level (IXXXX) shouldn't cause a failure. Or at a minimum personalities should be able to opt-in to it not failing without overriding the log output filter.
