Warning, treated as error:
.../swift/doc/source/overview_policies.rst:555:more than one target
found for cross-reference u'get_data_dir':
swift.obj.reconstructor.get_data_dir, swift.obj.replicator.get_data_dir,
swift.obj.diskfile.get_data_dir
Not sure why it hasn't been seen in the gate...
The whole sentence is suspect, though; the Diskfile class doesn't define
a get_data_dir method, though it uses the module-level get_data_dir...
