NAME__starget_for_each_device − helper to walk all devices of a target (UNLOCKED)

---

SYNOPSISvoid __starget_for_each_device(struct scsi_target * starget, void * data, void (*fn) (struct scsi_device *, void *));

---

ARGUMENTSstarget target whose devices we want to iterate over​. data parameter for callback fn() fn callback function that is invoked for each device

---

DESCRIPTIONThis 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​.

---

NOTEThe 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​.
