KfLowerIrql 函数

/*********************************************************************** NAME							EXPORTED*	KfLowerIrql** DESCRIPTION*	Restores the irq level on the current processor** ARGUMENTS*	NewIrql = Irql to lower to** RETURN VALUE*	None** NOTES*	Uses fastcall convention*/
VOID FASTCALL
KfLowerIrql (KIRQL	NewIrql)
{DPRINT("KfLowerIrql(NewIrql %d)\n", NewIrql);if (NewIrql > KeGetPcr()->Irql){DbgPrint ("(%s:%d) NewIrql %x CurrentIrql %x\n",__FILE__, __LINE__, NewIrql, KeGetPcr()->Irql);KEBUGCHECK(0);for(;;);}HalpLowerIrql(NewIrql);
}

相反还有一个提升IRQL级别的函数。KfRaiseIrql：下篇文章中呈现。
