IRQ_SET_AFFINITY_NOT(9) 				     Public Functions Provided					   IRQ_SET_AFFINITY_NOT(9)

NAME

       irq_set_affinity_notifier - control notification of IRQ affinity changes

SYNOPSIS

       int irq_set_affinity_notifier(unsigned int irq, struct irq_affinity_notify * notify);

ARGUMENTS

       irq
	   Interrupt for which to enable/disable notification

       notify
	   Context for notification, or NULL to disable notification. Function pointers must be initialised; the other fields will be initialised
	   by this function.

DESCRIPTION

       Must be called in process context. Notification may only be enabled after the IRQ is allocated and must be disabled before the IRQ is freed
       using free_irq.
