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.
