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

iterate over all devices of a host (UNLOCKED)

## NAME

\_\_shost\_for\_each\_device - iterate over all devices of a host (UNLOCKED)

## SYNOPSIS

**\_\_shost\_for\_each\_device(***sdev***,** *shost***);**

## ARGUMENTS

*sdev*

the struct scsi\_device to use as a cursor

*shost*

the struct scsi\_host to iterate over

## DESCRIPTION

Iterator that returns each device attached to *shost*. 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 to use this is because you need to access the device list in interrupt context. Otherwise you really want to use shost\_for\_each\_device instead.
