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.
