Bug in "df" on large drives |

Hello,
"df" contains a bug with large drives, I am assuming it is on those larger
than 8.4GB. I have an NTFS drive that is exactly 8,093,642,752 bytes large.
Here is what happens under Linux Kernel 2.4.0-test8.
"df -Th" results in:
address@hidden:/f/transfer/linux/ut# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/hdb7 ext2 494M 360M 108M 77% /
/dev/hda1 vfat 1019M 747M 272M 73% /c
/dev/hda5 vfat 1019M 962M 58M 94% /d

/dev/hdd iso9660 566M 566M 0 100% /cdrom2
address@hidden:/f/transfer/linux/ut#
on a system setup that looks like this:
cfdisk 2.10l
Disk Drive: /dev/hdb
Size: 12838404096 bytes
Heads: 255 Sectors per Track: 63 Cylinders: 1560

hdb6 Logical NTFS

hdb7 Logical Linux ext2 [TookyLinux]

You'll notice that the free space (3.1G) is correctly reported but the Size
and Used are obviously wrong (I wish I had 60GB..)
