# \_\_starget\_for\_each\_device(9)

helper to walk all devices of a target (UNLOCKED)

## NAME

\_\_starget\_for\_each\_device - helper to walk all devices of a target (UNLOCKED)

## SYNOPSIS

**void \_\_starget\_for\_each\_device(struct scsi\_target \*** *starget***, void \*** *data***, void (\****fn***) (struct scsi\_device \*, void \*));**

## ARGUMENTS

*starget*

target whose devices we want to iterate over.

*data*

parameter for callback *fn*()

*fn*

callback function that is invoked for each device

## DESCRIPTION

This traverses over each device of *starget*. It does \_not\_ take a reference on the scsi\_device, so the whole loop must be protected by shost-\>host\_lock.

## NOTE

The only reason why drivers would want to use this is because they need to access the device list in irq context. Otherwise you really want to use starget\_for\_each\_device instead.
