Re: [PATCH] struct thread_struct, asm-i386/processor.h: wrong datatype?

or better:

> -       unsigned long   gs;
> +       unsigned short  fs;
> +       unsigned short  gs;

>         unsigned long   debugreg[8];  /* %%db0-7 debug registers */
>  /* fault info */

+ unsigned short fs, __fsh; 
+ unsigned short gs, __gsh; 

which is also done this way the structure above, the TSS. I don't know
why it's done this way, but I guess it's probably better pad with 16 bits
to avoid potential problems with 32bit movl which might overwrite portions
of the next field.

kind regards,
