NAME

6       __starget_for_each_device - helper to walk all devices of a target
7       (UNLOCKED)
8

SYNOPSIS

10       void __starget_for_each_device(struct scsi_target * starget,
11                                      void * data,
12                                      void (*fn) (struct scsi_device *, void *));
13

ARGUMENTS

15       starget
16           target whose devices we want to iterate over.
17
18       data
19           parameter for callback fn()
20
21       fn
22           callback function that is invoked for each device
23

DESCRIPTION

25       This traverses over each device of starget. It does _not_ take a
26       reference on the scsi_device, so the whole loop must be protected by
27       shost->host_lock.
28

NOTE

30       The only reason why drivers would want to use this is because they need
31       to access the device list in irq context. Otherwise you really want to
32       use starget_for_each_device instead.
