#
# The __eq__ function works by using obj_to_primitive()
# and this includes a list of changed fields. Very
# occassionally the ordering of the list of changes
# varies, causing bogus equality failures. This is
# arguably a bug in oslo.versionedobjects since the
# set of changes fields should not affect equality
# comparisons. Remove this hack once this is fixed:
