Name
kstat_irqs_usr —
Get the statistics for an interrupt
Synopsis
unsigned int kstat_irqs_usr ( | unsigned int irq); |
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.
