+	   generic status bit GMT_CLN if a cleaning request bit pattern
+	   is found from the extended sense data. Many drives set one or
+	   more bits in the extended sense data when the drive needs
+	   cleaning. The bits are device-dependent. The driver is
+	   given the number of the sense data byte (the lowest eight
+	   bits of the argument; must be >= 18 (values 1 - 17
+	   reserved) and <= the maximum requested sense data sixe), 
+	   a mask to select the relevant bits (the bits 9-16), and the
+	   bit pattern (bits 17-23). If the bit pattern is zero, one
+	   or more bits under the mask indicate cleaning request. If
+	   the pattern is non-zero, the pattern must match the masked
