- __shost_for_each_device(sdev, shost);
- the struct scsi_device to use as a cursor
- the struct scsi_host to iterate over
Iterator that returns each device attached to shost. It does _not_ take a reference on the scsi_device, so the whole loop must be protected by shost->host_lock.
The only reason to use this is because you need to access the device list in interrupt context. Otherwise you really want to use shost_for_each_device instead.
