Can And BTW, this is why the function is only used when checking whether a task is frozen rather than to decide to issue freeze_task() on it, and it seems your change is correct now that we don't have per-task FREEZE flag but I can't say I like the change. I'd really like to keep things as dumb as possible for freezer.
