Hello.

Stat prints the device number, major and minor, in hex and decimal. They 
are both 8bit numbers clamped together. While the hex number is 
perfectly fine, the decimal doesn't respect how this number has come to 
existence. There is no meaning in the decimal value, if the the hex 
value is taken as one 16bit number and then converted.

For example "fd00h" is converted to "64768d". There is no major device 
with 647 and no minor device with 768. Its just completely wrong.

So instead of converting fd00h to 64768d, both 8bit hex numbers must be 
converted each, meaning alone. The right number would be therefore 
253000, major 253 and minor 0. While the hex number needs two digits 
each (the first 0 can be ommited), the decimal needs three digits each 
(the first and second 0 can be omitted).
