Some potential callers want to inject a hang into a particular context, some want to trigger an actual ban and others may or may not want to capture the associated error state. Expand the hang injection interface to suit all. v2: Disable the new kernel API, but push to provide a missing piece of infrastucture to unbreak compilation.
