__STARGET_FOR_EACH_D(9)                   SCSI mid layer                  __STARGET_FOR_EACH_D(9)



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.
