[PATCH] gdisk patches

[Mark Pustjens <pustjens@xxxxxx>]

Hi List,

Below a patch wich fixes two bugs in the gdisk package. They have been 
submitted uptream but not yet been accepted. The first bug fixed is that 
partition attributes are read/stored backwards. The second bug fixed is that 
when changing an undefined attribute no longer junk is displayed.

I'm not sure if this is the right place, but i sent to this list mainly because 
there is no official gpt fdisk list afai could find. Now this patch has a place 
on the net.

Cheers!

Greetings/Groetjes

Mark Pustjens
