However, I'm confused why programs would depend on it. If you froze a particular subsystem, you don't have to check. If you did not, what prevents whoever originaly froze it from unfreezing as you access it? As such, maybe the feature you are looking for would count how many times the fs is frozen. -- Mateusz Guzik -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
