# init\_copy\_desc\_masks(9)

copy cpumasks for irq\_desc

## NAME

init\_copy\_desc\_masks - copy cpumasks for irq\_desc

## SYNOPSIS

**void init\_copy\_desc\_masks(struct irq\_desc \*** *old\_desc***, struct irq\_desc \*** *new\_desc***);**

## ARGUMENTS

*old\_desc*

pointer to old irq\_desc struct

*new\_desc*

## DESCRIPTION

Insures affinity and pending\_masks are copied to new irq\_desc. If !CONFIG\_CPUMASKS\_OFFSTACK the cpumasks are embedded in the irq\_desc struct so the copy is redundant.
