now that 2.2.0 is approaching I'd like to get this one really to be fixed
(I first tried it in April 1996 and the patch below is still applies correctly!).
the output for my disk
SCSI device sda: hdwr sector= 512 bytes. Sectors= 8399520 [4101 MB] [4.1 GB]
^^^^^^^ ^^^^^^
is just wrong, because
4101 MB / 1024 == 4.00488 GB
which is _not_ 4.1 GB !!!

Hi Linus,
I like the new disk size message in sd.c but why is 1GB == 1000MB 1000* 2^20
and not 1GB == 1024MB == 2^30 ?
I'd really like to see "real" GBs as 2^30 (which would be more consistent
but just the opposite from what all the disk vendors thing a GB is
(or should be ;-))
Harald
