It may be a bad example - but think about things like page settings. Do you want a resume to scan in colour when you set black and white just before suspend ?

It should have refused to suspend because it was active

That sounds like nice design and horrible implementation - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
