cleaner_kthread() kthread calls try_to_freeze() at the beginning of every 
cleanup attempt. This operation can't ever succeed though, as the kthread 
hasn't marked itself as freezable.

Before (hopefully eventually) kthread freezing gets converted to fileystem 
freezing, we'd rather mark cleaner_kthread() freezable (as my 
understanding is that it can generate filesystem I/O during suspend).
