Subject: FAT : FAT16 support maximum 4GB file/vol size like WinXP or 7.

Hello Hirofumi

Win NT/XP/7 increased the maximum cluster size to 64KB, and file/vol
size increased 4GB also.

Although increasing , the file size of  linux FAT is still limited at 2GB.

I found that it is limited by sb->s_maxbytes(0x7fffffff) when
partition is formatted by FAT16.

I think that sb->s_maxbytes in fill_super should be set to 0xffffffff
like Fat32.

I want to know your opinion.

Thanks.
