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.
