Name

kstat_irqs_usr — Get the statistics for an interrupt

Synopsis

unsigned int kstat_irqs_usr (unsigned int irq);
 

Arguments

irq

The interrupt number

Description

Returns the sum of interrupt counts on all cpus since boot for irq. Contrary to kstat_irqs this can be called from any context. It uses rcu since a concurrent removal of an interrupt descriptor is observing an rcu grace period before delayed_free_desc/irq_kobj_release.
