+Contact: Ed L. Cashin <ed.cashin@xxxxxxx>
+Description:
+ (RO) Device status. The state attribute is "up" when the device
+ is ready for I/O and "down" if detected but unusable. The
+ "down,closewait" state shows that the device is still open and
+ cannot come up again until it has been closed. The "up,kickme"
+ state means that the driver wants to send more commands to the
+ target but found out there were already the max number of
+ commands waiting for a response. It will retry again after being
+ kicked by the periodic timer handler routine.
