Subjectgenirq default_disable()
From
Date
Folks,

A quick question about the interrupt management... (the story takes
place in kernel/irq/chip.c ;-)

Here we have the default_enable():

static void default_enable(unsigned int irq)
{
struct irq_desc *desc = irq_to_desc(irq);

desc->chip->unmask(irq);
desc->status &= ~IRQ_MASKED;
}

It calls chip->unmask(), which absolutely makes sense...

The default_disable(), however, is not symmetric:

static void default_disable(unsigned int irq)
{
}

Is there any reason why it shouldn't call chip->mask()?

I'll be more then happy to prepare a patch doing so, but maybe it's a
feature not a bug and I'm just missing something?

Best regards

Paweł
