PATCH 1/1 msdos fs: remove unsettable atari option

It has been impossible to set the option 'atari' of the MSDOS filesystem for several years. Since nobody seems to have missed it, let's remove its remains.

Looks good to me. Thanks.

Geert Uytterhoeven has a patch in his POSTPONED queue that is supposed to fix Atari FAT. I can't speak to whether it works or why it's postponed, but it seems to compile.

I see. Although I don't know the patch, I'd like to add this part to Geert's patch if possible. And when the patch can be posted, we can re-add this part again.

Geert, what do you think?

Geert, what do you think?

It's in POSTPONED state because nobody speaks up for/against it. Personally, I don't know how much it is (still) needed... But a few years ago somebody contacted me that he used it succesfully on PA-RISC and i386 ;-)

BTW, the patch is

Atari people, I think now is the time to let it live or die...

Gr{oetje,eeting}s,

Could you test whether it works well? If it works fine, I'll merge and clean it up. If it doesn't work, please fix it.

SECTOR_SIZE should be sb->s_blocksize? Or Atari doesn't support the sector size other than 512 bytes?

Thanks.

I haven't seen floppies with > 512 sectors. Atari partitioned harddisks use much larger sectors (up to 32 kB), of course.
