@ -274,7 +274,7 @@ sleep states and the hibernation state ("suspend-to-disk"). Each phase involves
executing callbacks for every device before the next phase begins. Not all
buses or classes support all these callbacks and not all drivers use all the
callbacks. The various phases always run after tasks have been frozen and
before they are unfrozen. Furthermore, the ``*_noirq phases`` run at a time
before they are unfrozen. Furthermore, the ``*_noirq`` phases run at a time
when IRQ handlers have been disabled (except for those marked with the
IRQF_NO_SUSPEND flag).
