Last question, doesn't wait_event_interruptible return immediately in
this case? signal_pending returns true due to non-captured signal which
killed the application and hence we are in the .release under these
special circumstances. I think this is not much expected behavior, is
it? Shouldn't be that signal dequeued/cleared instead?
